YMusic - A unique and innovative
YMusic (pronounce "Why Music") is a search
engine associated with a music database comprising approximately 39,000
analyzed tracks, a good part of which has an audio link to YouTube and/or
Spotify. It covers practically all styles and musical periods until today,
which allows interesting comparisons (Bach versus The Beatles, ...).
You can search for titles not only by metadata
(title, composer, ...) but mainly on the basis of specific musical
criteria, ie on the actual musical content of the tracks. This is the main
interest of this music search engine.
It is an experimental tool and its access is
completely free. The objective is twofold. On the one hand, it makes it
possible to compare different pieces on the basis of one or more musical
criteria. Thus, we can compare the harmonic richness, the use of melodic
intervals, the predominant rhythmic pulsations, the instrumentation, ...
on a set of pieces. On the other hand, you can create playlists based on
the search results, listen to them and export them to YouTube and/or
A remark is needed regarding the results
obtained through a research. The analysis of the musical content was
carried out on the basis of the content of the score or an equivalent file
and not extracted from the audio content. Although the corresponding
YouTube and Spotify audio links have been selected with great care,
sometimes the audio link is slightly different from the analyzed score.
These are often different interpretations, arrangements for other
instruments, simplifications, etc. Usually the musical criteria match
well, but variations or inaccuracies are therefore possible and
inevitable, due to the method by which the database was created.

The help button "?" to the right provides a
quick access to this manual. In the upper right corner of each panel, you
will also find a "?" icon that links to the specific help for that panel,
as well as a closing box allowing to close this panel more easily.
When the application is launched, the first two panels are visible. Adjust
the visible panels to suit your use and to maximize visual space. A
typical use would be as follows.
- You use the search panel to specify the criteria to search, then
you view the list in the results panel.
- To analyze in more detail and compare, you can open the Graphs or
Similarities panels and, depending on the case, close the main list
- To build a playlist, open the corresponding panel and close the
Search panel to save space.
The 6 following sections explain in detail
how to use the 6 panels of the YMusic application in order to make the
most of them.
2 - Search Panel
This panel allows you to define the criteria
on the basis of which to perform the search. At launch, it looks like
The first line allows you to define the
maximum number of results to display, between 100, 500 and 1000, as well
as the presence of the type of audio link required. More than 80% of the
titles have an audio link. If your goal is to create playlists, you better
have at least one audio link. If you just want to analyze, you can choose
the option "With or without audio link". You can also request the presence
of links specifically on YouTube or Spotify.
The following 4 lines are the categories of
criteria that can be used. The first allows you to search using basic data
of the score, such as tempo, key signature, instrumentation, ... The next
allows more advanced searches on the type of musical content (notes
present, durations, harmonies, intervals, ...). Then you have a text
search category by the title, the composer, the style, ... A last category
allows a text search on all the associated metadata.
The last line allows you to save search configurations with their results,
so that you can retrieve them later.
Let us see in detail the content of these zones.
Basic score information research
By clicking on this line,
the search box opens and looks like this:
7 basic musical criteria
are available. In order to perform a search on one or more of these
criteria, all you have to do is click on the corresponding line, which
brings up sliders allowing you to define the range of values to be
searched. For example, if you click on the mean tempo value, you get this:
By default, the sliders
are set to extreme values, which means that all titles will be included
for this criterion. By modifying these values you can for example filter
the titles which have a tempo between 100 and 120.
Opening the settings
associated with a criterion also has the consequence of listing the values
of this criterion in the list of results obtained. So, if you want to
compare the tempo values of a set of titles, without limiting the tempo
itself, you can open this setting and the results list will give you a
column that will show the tempo of all the resulting tracks. This is valid
for all musical criteria: to view them in a column, you must display the
search settings that correspond to them, even if you do not modify these
settings. You can open more than one at the same time.
Conversely, the settings
areas which are closed will not be taken into account for the search, even
if you have defined search parameters in them.
Note that when you search for multiple criteria at once, the given ranges
must all match for a title to appear in the results. It is therefore a
logical "AND" search. For example the tempo must be within a certain range
AND the length of the song must be within a certain range.
The Search YMusic
button is used to launch the search, the results of which will
appear as a list in the right part of the screen. The Clear
button resets all search areas. You will find these two buttons duplicated
in the other categories of search criteria.
Here are details on the 7 basic criteria.
You can specify a minimum
and maximum duration, in minutes and seconds, for the total duration of
the searched titles. By specifying for example "From 30 seconds to 1
minute", only the titles which duration is in this range will be
selected in the results.
Mean tempo value
Specify the tempo range
for the searching. The tempo is expressed in beats per minute. A value of
60 represents a tempo where each beat lasts one second. The beat depends
on the type of measure present in the song. A measure of 4/4 or 3/4 for
example will be measured in quarter note tempo. A 6/8 measure will be
measured in dotted quarter note tempo.
The tempo variation
measures the average difference between the basic tempo and its evolution
in the track. A piece that has a fixed tempo for the duration of the track
will have a tempo variation of zero. So the higher this number is, the
more the track has variations of tempo. Mathematically this is the
standard deviation of the tempo values encountered in the track.
Number of measures
in the score
It is simply the number
of bars present in the song. A measure (or bar) is a time division
of the song. A measure of 4/4 has 4 beats of a quarter note.
Number of beats in
It is simply the number of beats present
in the song. A measure of 4/4 has 4 beats of a quarter note. So if the
piece has 20 measures, then it has 20 x 4 = 80 beats. Measures can be
combined in a song and the value of the number of beats is the sum of
all the beats of all the measures in the score.
This area is more
extensive and allows you to search for the type of key signature(s) found
in the score. A key signature indicates the accidentals of the notes to be
used (the equivalent of black / white notes on a piano keyboard). A key
signature is specific to musical notation and does not necessarily
represent a perceptible musical characteristic. Indeed, the key indicates
the number of flats or sharps displayed by default on the staff, but each
individual note can be played with its own accidental. So in theory you
can write any music in any key signature and it will sound exactly the
same. In practice, we choose a key signature according to the majority of
the altered notes that are in the piece, and therefore we will say that
such and such a piece is written in D major, which implies that most of
the F and C notes are altered with a sharp.
To filter titles based on
key signature, you can:
- Choose the number of different key signature(s) that are present, by
default between 1 and 15, which includes all the pieces of the data
base, since there are only 15 possible different key signatures. By
choosing for example between 1 and 1, you will only find the pieces
which have a single fixed key signature for their entire duration.
- You can choose the main key signature of the piece, that is to say
the one which is the majority if there are several.
- You can choose the key signature in which the track starts, that is,
the key signature in the first measure of the track.
- Then you can choose the specific presence of one or more given key
signature(s), in percentage. By choosing, for example, a key signature
from 100% to 100% in A Major, you will only find pieces written
entirely in A Major. By choosing two key signatures between 25 and
100% each, you will find titles that have at least these two keys in
these proportions. To add or remove a choice of key signature, use the
two buttons + and -.
Similarly to key
signatures, here you can select titles based on the time signature in
which they are written. The time signature determines how beats are
grouped in a track and gives an overall rhythmic feel to the song. For
example we can easily distinguish a 4/4 time signature (most rock is
written in this time signature) from a 3/4 time signature which is the
typical example of a waltz, binary / ternary opposition. There are many
different time signatures and we have listed 20 of them. The 21st choice
represents all the other possible measures not listed (like 7/8, 9/4, ...
which are much less frequent).
Here you can filter the time signature as follows:
- Choose the number of different time signature(s) that are present,
by default between 1 and 21. By choosing for example from 2 to 2, you
will find the parts which include exactly two types of time
- You can choose the main time signature of the track, that is to say
the one which is the majority if there are several.
- You can choose the time signature in which the track must start, ie
the one present at the first measure of the track.
- Then you can choose the specific presence of one or more given time
signature(s), in percentage. By choosing, for example, a time
signature of 3/4 from 100% to 100%, you will only find tracks written
entirely in 3/4. By choosing two time signatures between 25 and 100%
each, you will find titles that have at least these two measures in
these proportions. To add or remove a choice of time signature, use
the two buttons + and -.
music criteria research
Here you will find 7 musical criteria, each of
which has several different aspects. The principle is to analyze the
presence and distribution of the musical elements which form the music
itself, i.e. the pitch of the notes, the duration of the notes, the
intensities of the notes, the sounds that play these notes, the rhythmic
pulsations, the melodic intervals and the types of harmonies. Distribution
means the way in which these different elements are present and in what
Let's take a look at each distribution in detail.
The pitch of a note is simply the frequency
of vibration of the air that transmits it. To represent pitch, we use a
number between 0 and 127, which is the standard representation of notes in
a MIDI file. The value 60 corresponds to the central C note of the piano,
the one located below the G-clef staff. Each unit represents a semitone.
So, the value 61 represents a C #, 62 represents a D, ... a jump of 12
semitones represents an octave, so the value 72 represents the C note one
octave higher than the central C. The value 0 corresponds to a very low C,
even lower than the lowest note of a piano.
Here are the criteria that allow you to select titles according to the
notes that are present.
Mean value of the pitch
It is the average pitch of all the notes
present in a song. If the average is for example 60 (central C of the
piano) it could be a simple melody which evolves a few notes around C. But
it could also be a full orchestral piece, which covers the whole range
from very low to very high, but whose midpoint is on central C. By default
the search suggests between 0 and 127, which places no limit. You can
specify a minimum value and a maximum value. You will get all of the
titles whose mean values fall within this range.
Dispersal value of the pitch
The dispersion value makes it possible to
better distinguish the two situations described in the previous point. It
is a measure that expresses how the pitches deviate from the average. A
very small dispersion value will indicate that the notes in the track are
all very close to the average value. A value of zero, an extreme case,
represents a melody that always repeats the same note throughout the
track. A high dispersion value would be found for example in a complete
symphonic orchestration, because the piccolo would be very high and the
double bass very low, both very far from the central note. You can
therefore specify a dispersion range and get all the pieces that satisfy
it. If you place for example the minimum at zero and the maximum at 5, you
will obtain titles whose notes do not deviate very much from a central
Different values of the pitch
Here, the search is made on the number of
different notes used in the track, regardless of where those notes fall
within the full possible range of pitches. A minimum and maximum value of
7 will give you all titles with only 7 different pitches (each of which
may appear multiple times).
Lowest value of the pitch
Here the search is done on the lowest note of
a track. If you set the minimum value to 60 (central C), all titles with
at least one note lower will be excluded from the search.
Highest value of the pitch
Similarly, the search is made on the highest
pitch of a track, choosing the minimum value and the maximum value.
Range of the pitch
The range represents the
difference between the highest note and the lowest note. For example, by
setting the maximum range to 12 semitones, it is then possible to select
only the titles whose notes cover a maximum of one octave, without
constraint on the position of this octave (this could be a full octave in
very low notes or a full octave in the high notes).
Each note in a piece of music has a specific
duration. This criterion makes it possible to select titles on the basis
of the durations of the notes. An arbitrary numbering of the durations is
used. A value of "1" represents the duration of a 32nd note, in the tempo
of the track. So a duration of 8 represents a quarter note, which usually
corresponds to the tempo. Let's take the example of a track with a tempo
of 60 per quarter note, where each beat (quarter note) lasts one second. A
value of duration "8" corresponds to 8 32nd notes, which is a quarter
note, lasting one second. A value of "1" would be an eighth of a quarter
note, so an eighth of a second. A value of "16" corresponds to two
quarter notes, therefore one half note, which has 2 seconds of duration.
If the tempo changes, this value changes in the same proportion. It is
therefore a scale of relative values of note durations within the same
Given this numbering convention, here are the search criteria which allow
you to select titles according to the length of notes present. Note that a
value of zero corresponds to any note that is shorter than the 32nd note
(grace notes, trill, 64th note, ...).
Mean value of the duration
The search is carried out on the average of
the duration of the notes of the score. Select a minimum and maximum
duration value and you will get titles with average duration within the
specified range. Similar to the example given for pitches, an average of
"8" for example (quarter note) simply means that the average duration of
notes is one quarter note. This could be a song consisting of quarter
notes only, but also a song that had a balance of half notes and eighth
notes, with no quarter notes present. Or any other combination whose
average would be around a quarter note.
Dispersal value of the duration
This criterion makes it possible to
distinguish the two situations expressed in the previous point. How far do
the note durations deviate from the average note duration of the entire
track ? You can specify a minimum and maximum range and get all the titles
that match. By specifying a small range, for example 2, you will find
tracks with most notes of similar durations.
Different values of the duration
Here you can search based on the number of
different note durations in a song. By specifying a maximum value of "1",
you will find all the titles of which all the notes have the same duration
for the whole track. A value of "2" will give you titles that only have
two values of different durations.
Shortest value of the duration
Here the search is done on the shortest
duration of the notes of a piece. If you set the minimum value to 8
(quarter note), all titles with at least one shorter note will be excluded
from the search and only tracks with all notes equal to or longer than a
quarter note will be found.
Longest value of the duration
Similarly, the search is done on the longest
note of a track, choosing the minimum value and the maximum value.
Range of the duration
This is the difference between the shortest
and the longest duration. By limiting the range, you exclude titles that
have very disparate durations. A maximum value of zero will give you
titles with only one note duration.
Each note in a track is played with a given
intensity. We call this the dynamics, which are distributed conventionally
from a quadruple piano pppp to a quadruple
forte ffff written in the
musical score. We have divided the intensities into 16 arbitrary zones,
representing a scale of the zones of possible intensities and these are
numbered from 1 to 16. Given this numbering convention, here are the
search criteria that allow you to select titles depending on the
intensities of the notes present.
Mean value of intensity
All the notes of a piece are sorted by
intensity category and here you can filter the titles by the intensity
categories present. As it is an average, it gives an idea of the average
position of the intensities. By asking for a low average, you will have
pieces written with soft volume intensity.
Dispersal value of intensity
The greater the dispersion, the more
contrasted the title will appear when listening to it. This value
indicates how far away the intensities are from the average value for the
Different values of intensity
Another way to manage intensities is to
impose that the track has a minimum or maximum of different intensity
values. By setting a value of "1" as the maximum, you will find tracks
that have a unique, monotonous intensity throughout the length of the
Lowest value of intensity
Here the research is done on the lowest
intensity of the notes of a piece. If, for example, you set the minimum
value to 12, all tracks with at least one lower note intensity will be
excluded from the search and only those songs where all the notes are
played loudly will remain.
Highest value of intensity
Similarly, the search is done on the highest
intensity note of a song, choosing the minimum value and the maximum
Range of the intensity
It is the difference between the weakest and
strongest intensity present in a song. If you set a value of "0" as the
maximum, only the tracks with a monotonic intensity will remain. By
imposing "15" you will obtain pieces with a strong contrast in intensity.
Each note in a track is played with a
specific instrument. This criterion makes it possible to search for tracks
on the basis of the instrumentation used in the analysis of the database.
The proportions are given in number of notes played per instrument.
Number of different instruments
Allows you to select the number of
instruments involved in the searched titles. By setting the maximum to "1"
you will obtain all the titles comprising only one instrument (soloist).
By specifying a minimum of 10, we will obtain titles with already
substantial instrumental ensembles. Here we do not take into account the
proportions, there could be one saxophone note and everything else on the
flute, the result would nevertheless be two different instruments.
The search element at the bottom of the
frame allows multiple searches to be performed on the proportion of
specific instruments. You can search by specific instrument, percussion
instrument, or instrument category. The drop-down menu then allows you to
specify the instrument or category. Then choose a required proportion rate
between 0 and 100%. The search will filter the titles based on this.
By using the "+" and "-" buttons you can add / remove another instrument
to search. A practical example would be for example minimum 50% piano and
minimum 20% violin and you will find many pieces for piano and violin. By
limiting to 2 instruments, you will only find tracks with piano and violin
to the exclusion of any other instrument.
Rhythmic harmonic distribution
A rhythmic harmonic is simply an integer or
fractional multiple of the main beat imposed by the tempo. Let's take the
example of a piece written in 4/4 at a tempo of 60. We therefore have one
beat per second, which is represented by quarter notes. The quarter note
is here the rhythmic harmonic "1". The rhythmic harmonic "2" is twice as
fast, so it's eighth notes. Harmonic "3" will be represented by eighth
note triplets. Harmonic "4" will be sixteenth note, and so on. In the
other direction, we can also divide and consider the rhythmic harmonic
"1/2", which means that the frequency of this rhythm is divided by two
(its duration is multiplied by two) and we therefore have in our example
the rhythmic harmonic "1/2" represented by a half note. "1/4" will be the
whole note, etc.
Tempo is usually representative of the main
cadence the song follows, the sense of perceived speed at which the track
is played. The notion of rhythmic harmonic refines this perception of
speed. If the tempo is the main beat, then the distribution of rhythmic
harmonics more subtly represents the impression of speed felt when
listening to the track. We could indeed have a piece that is played at
quarter note equal 60, where this quarter note duration is the main,
accented beat that drives the music. And on the other hand, the presence
of faster secondary rhythms: the higher rhythmic harmonics. The more there
are, the more one will have the impression that beyond the main beat,
there are fast things happening in the music playback.
So a piece at a tempo of quarter note = 60
with a strong "4" harmonic and a weak "1" harmonic will give the
impression of a fairly fast track, despite the tempo being a moderate
tempo at the base.
This criterion therefore makes it possible to distinguish the way in which
the rhythmic harmonics are represented and to carry out a search on this
basis. It is divided into 5 different sections.
Different values of rhythmic
This criterion makes it possible to determine
the number of rhythmic harmonics present in the searched titles. By
setting the maximum very low (1 or 2), you will obtain titles with small
rhythmic diversity. Conversely, by searching for titles on a basis of a
high minimum (10 and +), the selected tracks will be richer in rhythm.
Main rhythmic harmonic
Allows you to search on the basis of the
majority rhythmic harmonic in the titles. Thus, a majority harmonic of "2"
will find the titles where the eighth notes are the most numerous
rhythmically. A "3" harmonic will give titles based on ternary rhythms,
Slowest rhythmic harmonic
Here we search for titles based on the
slowest rhythmic harmonic found. By taking a minimum of "1", the resulting
titles will have all their rhythmic harmonics equal to or greater than 1.
Fastest rhythmic harmonic
Conversely, we select here on the basis of
the fastest rhythmic harmonic found in a title.
Presence of individual rhythmic
Here you can perform a precise search for the
presence of one or more specific rhythmic harmonics. The 16 harmonics
taken into account are presented as 16 settings, which cover by default
all cases, from 0 to 100%. To find a song that would have a lot of quarter
notes and a many eighth note triplets, you could start the search with:
harmonic 1 between 50 and 100%, harmonic 3 between 30 and 100% and then
refine the settings according to the results obtained.
Melodic interval distribution
The melodic interval is the distance between
two successive notes of a melody. It can be ascending or descending, small
or large. It is measured in number of semitones, positive for an ascending
interval, negative for a descending interval. Music theory also
gives precise names to qualify them, such as a minor second, a unison, a
major third, ... YMusic's analysis is made on the basis of intervals
ranging from minus two octaves (-24 semitones) up to two octaves (+24
semitones). This analysis only covers the melodic parts of the analyzed
piece, that is to say instrumental parts which only include one note
played at a time. If there is a string section that plays chords, that
section is not taken into account for melodic analysis. It could therefore
be that a purely chord accompaniment piece would not contain melodic
intervals, since no individual melody is present. Here are the criteria
that allow you to refine a search based on the types of melodic intervals
Presence of melodic intervals
This setting allows you to specify the
minimum and maximum presence of one or more melodic intervals. A drop-down
menu lists the possible intervals, under their usual musical name, which
corresponds from top to bottom respectively from +24 to -24 semitones. By
choosing a minimum of 100% of a given interval, we will find (if they
exist) the titles comprising only this interval.
To specify the presence of several melodic intervals, use the "+" and "-"
buttons, which add a search area combined with the previous ones.
Mean value of melodic intervals
By taking the mathematical average of all the
melodic intervals found in a track, we get a value that can be searched.
By asking for a positive mean interval, we will obtain titles which
melodies are more ascending than descending, and vice versa.
Melodic interval dispersal
This number represents how the melodic
intervals deviate from the average melodic interval of the track. The
greater the dispersion, the richer the melodies of the selected titles
Melodic interval directions
Here the search is made on the basis of the
type of interval: up, unison (repetition of the same note) or down. For
example, you can determine that the melodies you are looking for will have
at least 25% repetition and at least 50% ascending intervals.
Different melodic intervals
Used to specify the number of different types
of intervals found in a searched title. The richness and extent of the
melody will depend on it.
Smallest descending melodic interval
The search is carried out on the basis of the
smallest descending melodic interval which is present in the searched
Largest descending melodic interval
The search is carried out on the basis of the
greatest descending melodic interval which is present in the searched
Smallest ascending melodic interval
The search is carried out on the basis of the
smallest ascending melodic interval which is present in the searched
Largest ascending melodic interval
The search is carried out on the basis of the
largest ascending melodic interval which is present in the searched title.
The idea here is to carry out a search on the
basis of the harmonies present, therefore on the combination of the notes
played simultaneously, what is more commonly called chords. Here are the
different researches that can be done on this principle.
Polyphony is the number of notes played
simultaneously by all the instruments present. For a solo piece for flute,
this number will always be "1", or "0" when there is a rest in the score.
And for a full orchestra, it could have several dozen notes. So this
criterion makes it possible to select titles on the basis of the greatest
polyphony found. A maximum value of "1" will result in all single-note
solo instrument pieces.
Conversely, you can search on the minimum
number of notes played in a title.
Largest reduced polyphony
If we analyze a chord played by a full
orchestra, although there might be several dozen notes, we will usually
find many notes duplicated one or more octaves higher or lower. We could
therefore have 5 C notes at various pitches. These C notes will reinforce
the harmony present but will not really change the type of chord played.
So the idea here is to "reduce" the polyphony to the 12 base notes of one
octave and see how many different notes you hear at once. This will depend
on the richness of the present chord, regardless of the fact that several
of these notes are duplicated in other octaves. This number is referred to
here as reduced polyphony and is between "0" and "12". By imposing a
minimum of 4 or 5 notes of reduced polyphony, the richness of the harmony
heard will be greater.
Smallest reduced polyphony
Same principle, based on the smallest reduced
The idea here is to detect the richness of
harmonies per unit of time, specifically, the number of different
harmonies present in one minute of music. The larger it is, the richer and
more diverse the harmony will be. The search can be made on the basis of 4
numbers, each time in a range determined by you:
- On full polyphony, as explained above
- On reduced polyphony, as a single octave
- On full polyphony transposed in C
- On reduced polyphony transposed in C
When specifying "transposed in C", it means that the lowest note present
in the harmony serves as the basis for a transposition to the note C, all
the notes present being transposed in the same way. In practice, this
makes it possible to detect the types of chords present. For example, if a
piece has on the one hand a D major chord (D, F #, A) and an A major chord
(A, C #, E), these 2 chords are placed on two different notes (D and A )
but are both part of a single family of chords, in this specific case the
"Major" chord. So by bringing all the chords found towards the note C, we
will only find in this case one type of present chord, the "Major" chord.
We can therefore carry out the search on this finer basis if desired, ie
detect the different types of chords, regardless of their bass note.
Presence of harmony types
YMusic's analysis defines 32 different
harmony classes. On the one hand the single note (which is a rudimentary
harmony in itself), then the intervals, i.e. two notes played at the same
time (a major third, a minor seventh, ...) and then the different types of
chords with 3, 4, 5 notes and more.
The first criterion allows you to choose the number of types of harmony
present in a track. The bigger it is, the richer will be the harmony
perceived in the whole piece.
The following element can be duplicated using the "+" and "-" buttons in
order to perform a specific search on the proportion of presence of given
harmonies in a track. The desired harmony is specified via a drop-down
menu and its proportion range can be defined by two sliders between 0 and
Presence of harmony inversions
A chord based on a given note can contain
that root note as the lowest note of the chord, for example the C major
chord with the notes C, E, G. This is called the root position of the
chord. But this same chord can be "inverted", that is to say from the
lowest to the highest, be in the order E, G, C. This is the first
inversion. It changes the sound color a bit when listening, but keeps a
family resemblance with its root chord. In the same way one can invert in
the order G, C, E, it is the second inversion. A 4 or 5 notes chord may
include a third or fourth inversion.
This criterion is used to determine which types of position the chords use
in the searched tracks. You can specify a limit range between 0 and 100%
for each position.
Combining musical search criteria
As already mentioned, you can combine all of
these criteria to perform more complex and personalized searches.
By opening this area, you can perform a text
search on the title, composer, performer and style. The set of titles is
divided into no less than 880 different styles, themselves grouped into 24
general categories, which you can search via 24 check boxes. Some of the
titles also include the year of composition. The titles which do not
include it have a year equal to zero. You can therefore also include the
year in your search criteria.
This search can be combined with all the musical criteria explained above.
This area allows a global text search on all
the metadata present (title, composer, style and performer). Here too you
can combine it with the music search criteria.
When you set up a search, you can save it so
that you can retrieve it in the future. This is especially useful if your
search has many parameters chosen and adjusted to obtain a specific
result. For this function to be active, you must open a YMusic account and
be connected to this account. It's completely free and you can get it in
30 seconds via the panel titled "My Account
". Without an
account, this area remains grayed out and unusable. If you have an
account, make sure you're signed in to it, in the same panel.
To save your search, give it a title in the text box to the right of the Save
this research as
button and then click this button. Your search
is added to the drop-down menu entitled My Researches
which is just above it. To retrieve a previously saved search, select it
from the drop-down menu and click the Load
search panels will then restore the same settings and automatically launch
the search to obtain the results in the list on the right.
By using the Delete
button, you can simply delete this
search from your account.
3 - Results Panel
This panel is basically a list. This is
where the results are displayed. By default, the columns of the list
include the title, style, year, composer and performer.
According to the criteria you specified in the search panel, the numerical
values and the distributions of these criteria are also displayed in
columns. For a criterion to be displayed in this list, it must be open in
the search panel, even if you do not specify a value limiting the
criterion. For example, if you carry out a search on the pitches of notes
present, by specifying and limiting these criteria, you can, without
making it restrictive, also display the duration of the titles found as
well as their tempo, by simply opening these two criteria of duration and
You can adjust the column width by clicking and dragging the column
separator line. By clicking in the title of a column, you can sort this
column in increasing values. By clicking a second time, the sort is
descending. By clicking a third time, it returns to the default sorting,
with the titles displayed in alphabetical order.
Some criteria include a distribution indicating the proportions of the
presence of a series of possible values. For example, if you turn on a key
signatures search, you will see a Key signature distribution column appear
in the list, which looks like this:
In this specific case, it displays the
presence of the 15 possible key signatures, between 7 flats (completely to
the left) and 7 sharps (completely to the right). The column is therefore
divided into 15 sub-columns, each of which can display the presence of a
type of key signature by a blue rectangle which height represents the
proportion present in the title in question. By dragging the mouse over
these rectangles, you will see a small text appear indicating the
proportion present in percentage, as well as the type of key signature in
question. This visual representation makes it easy to get an idea of
what the different titles displayed in the list contain. The search is
not done directly on a distribution, but the distribution helps to view
the data in a table. For distributions that have many sub-columns, you can
widen the column in question to have greater precision in examining it.
By clicking with the right mouse button, you can select the visible
columns in the list.
By clicking on a line, you can select it.
By clicking on a line while holding the SHIFT key, you can extend the
already existing selection to the new clicked line.
By clicking on a line while holding the CTRL key, you add (or remove, if
it is already selected) that line to the selection.
Just above the list, YMusic mentions the
number of tracks that have been found. A button allows you to select all
the lines in the list. Another button allows you to add all the selected
lines to the playlist. This last button will also open the playlist panel
if it is not already visible.
4 - Graphic Panel
When a search is performed, you can use this
panel to view the numerical data in graphical form. For this, there must
necessarily be numbers in the columns of the search results, otherwise the
graph is of no use.
The idea of this graphic is to position each title as a point in an area
with X and Y coordinates. Two drop-down menus allow you to specify the
musical criteria taken into account to position the title on the X axis
and the Y axis. An additional drop-down menu allows you to determine the
size of a point to represent one of the musical criteria.
Here is a practical example where a hundred titles are represented:
With the settings chosen here, a title is
positioned as high on the graph than its tempo is high, as much to the
right as the duration of the piece is long, and the size of the point
indicates in a relative way the number of key signatures present in this
To use the graphics panel more comfortably, you can close the other panels
so that the graphics takes up the full size of the screen.
Once this graph is displayed, you can:
- Hover the mouse over the different points: a text at the bottom of
the panel displays the title in question and its precise values.
- By holding down the right mouse button you can use the mouse wheel
to zoom in to better examine an area.
- When you have increased the zoom and still holding the right mouse
button, you can move the mouse to move around the graph to examine a
specific area. Combine the zoom of the mouse wheel with just moving
- By clicking (with the left button) and dragging the mouse, you can
draw a rectangle which allows you to select the corresponding points
(titles). These will also be selected in the list of results (and vice
versa). By drawing a selection rectangle while holding down the SHIFT
key, you add the points to the current selection. And with the CTRL
key, you reverse the points surrounded by the rectangle.
Another mode can be used to view the
distribution of the values of a criterion. To do this, in the drop-down
menu of the Y axis, choose the first choice entitled Quantity and
in the drop-down menu of the X axis, choose the musical criterion you wish
to analyze. You will obtain a different graph, showing the quantity of
titles present in each horizontal slice of the criterion in question. Here
is an example for the duration of the title:
In this example, we can read this graph as
follows: there are 17 titles that have a duration between 330 and 478
seconds (third rectangle).
5 - Similarities Panel
This panel makes it possible to establish
the similarity of all the titles on the basis of a reference title. When
you open this panel, it is empty. Double-click on a title in the main
results list, on the basis of which you want to perform the comparison.
This title will then appear in the comparison list, in first position, as
well as all the other titles, classified in the order of similarity to the
The list has a column entitled Similarity expressed as a
percentage. The first line is the reference title, so the similarity of
this title to itself is necessarily 100%. The rest of the list displays,
in descending order of similarity, all of the other titles that were
selected in the search. Here is a practical example, where we used the
criteria of tempo, range of note pitches and distribution of note pitches.
The similarity is calculated on the basis of
the selected criteria and you can weight these criteria via the sliders on
the left. If there are three criteria set at 100 percent like here, it
means that the percentage of similarity is calculated equally on the three
criteria. In other words, in this example, to have a total similarity
(100%) it is necessary that the tempo of the two compared titles is
exactly the same, that the range of the pitches corresponds perfectly and
that the distribution of the pitches is exactly the same. The percentage
in the Similarity column therefore gradually decreases for the
titles compared, all the more so as these three criteria deviate from the
values of the reference title.
By changing the settings of the left sliders, you can change the
importance of each criterion in the comparison. When you modify these
settings, it is then necessary to click the Build the list of
titles with similarities button in order to recalculate the
similarities of all the titles taking into account this change in
weightings. For example, if you keep the first criterion at 100% and the
other two at zero%, then you might have a few more titles that have 100%
similarity to the reference title. This limits the comparison to a single
criterion. So we can say that two tracks with the same tempo are 100%
similar, based on a tempo comparison only. It is therefore
always a relative similarity that this table makes it possible to
establish, on the basis of one or more selected criteria and in the
proportion that you decide.
You can also select lines from this list, in
a similar way to the main results list and two buttons allow you to select
everything or add the titles to the current playlist.
This comparison feature, used on many criteria and titles, makes it
possible to find titles which have important musical similarities and
which are therefore likely to please someone who would very much like the
title used as a comparison reference. This is a start of a "music
recommendation" type of functionality, but here based on the actual
musical content and not on the basis of song listening statistics and an
analysis of the type "Fans also like ...".
6 - Playlists Panel
This panel allows you to build playlists
based on the titles you have selected through searches and also sorted
according to a similarity determined by you.
The two lists (results and similarities) allow you to add titles to the
current playlist (which is initially empty).
The playlist also displays a title list, with a column titled Y / S. The
presence of a Y for a title indicates that there is an audio link that can
be listened to via YouTube. The presence of an S indicates the presence of
an audio link that can be listened to via Spotify.
Four buttons are present just above the playlist, respectively allowing to
clear the playlist, to remove the selected title, to move up or down the
selected title (in order to modify the order of the playlist).
Below the playlist are three tabs.
The first tab allows you to save playlists in
order to recover them in the future. It is only active if you have a
YMusic account and are logged into it. Having a YMusic account is
completely free and you can get it in 30 seconds via the panel titled "My Account". Without an account, this area remains grayed
out and unusable. If you have an account, make sure you're signed in to
it, in the same panel.
To save the current playlist, give it a name
in the text box to the right of the Save this playlist as
button and then click this button. It is then added to the drop-down menu
entitled My playlists. To retrieve a playlist, select it from
the drop-down menu and click the Load button.
The Delete button allows you to delete a playlist from
By clicking on the YouTube Player
tab you get a basic player which allows you to listen to the title
selected in the playlist, as long as this title has a YouTube audio link.
For the YouTube player, you can also start the playlist by double-clicking
a title. At the end of the playback of this title, the next one will be
By clicking on the Spotify Player
tab you get the official Spotify player, which is less flexible to use
than the YouTube player. A double click on the title cannot start this
player or link the other titles. Specifically, you need to use the
player's Start button presented by Spotify. If you don't have a Spotify
account, you will only be able to listen to 30 seconds of the track in
question. If you create a free account on Spotify (which you can do on the
Spotify site), then you can have access to the full duration of the
titles. For this, you must be connected to the Spotify account through
your Internet browser, whether it is a free or paid account.
You can also export your playlists to YouTube
and Spotify. The two buttons that allow this are in the Save /
Restore Playlists tab. The procedure is different for YouTube and
The Watch this playlist on YouTube...
button creates a link that opens directly in a new tab in your browser on
the YouTube page. This link actually creates a temporary "unlisted"
playlist. You can listen to it directly on YouTube. It seems that
YouTube's new interface no longer allows you to copy this temporary
playlist at once to a playlist in your account. It is still possible to
copy each video separately to a playlist in your account. You must of
course be logged in to your YouTube account.
For Spotify, click the Export this
playlist to Spotify button. Then open the Spotify application
on Windows or Mac (the procedure does not seem to work if you are using
Spotify directly in the browser). Create a playlist on your account and
once it is displayed you can simply use the keyboard shortcut CTRL + V to
paste the playlist there. You can do the same with an existing playlist,
to add tracks from YMusic.
7 - User Account Panel
This panel allows you to create or log into
a YMusic account. A YMusic account is free and simply allows you to be
able to save searches and playlists made with YMusic.
To create an account, click the Create an account ...
button and define a username, a password, as well as your email address
and your choice of whether or not to receive the YMusic newsletter, then
click on the Register button.
The application then tells you that you are well connected. If you check
the Stay connected box, a cookie will be saved and you will
automatically stay logged in for your future visits to the YMusic site.
If you are not logged in, simply enter your username and password and you
will be logged in.
A Can't remember my password... button allows you to
enter your username and YMusic will send you a new password to the email
address provided during registration.
When you are logged in, you can modify your account settings at any time
using the Edit account button. You can modify the
password, the email address and the choice to receive or not the YMusic
