Group Music According To Categories |
Suppose
you are asked to give some examples of music styles. What would
you give as music styles? You may give general categories such
as "rock" and "jazz". On the other hand, you may give more
detailed categories such as "hard rock", "British rock", and "AOR".
Numerous music styles can be classified
hierarchically. |
| Music |
| Classical Music |
| Orchestra |
| Piano |
| Chamber Music |
|
| Popular Music |
| Rock |
| AOR |
| Hard Rock |
| Heavy
Metal |
| Ballad |
|
| Jazz |
|
| Fusion |
|
| Blues |
|
|
| Ethnic Music |
| Indian Music |
|
| Japanese Music |
|
| Indonesian
Music |
|
| Hawaiian Music |
|
|
|
|
However, as you can see from the above classification,
each music style or musical genre is crossed each other.
Therefore, it is difficult to group them by strict standard.
For example, with above classification, ballad is classified as
rock, but jazz also has ballad tune. So in this sense,
music style is crossed each other. |
|
In order to compose tunes according to these music styles,
characteristics or features of each music styles are changed
into parameters in ACS. Various parameters such as musical
scales, musical instruments, and harmony patterns are ready to
use in ACS. |
|
|
|
|
Create New Style By Mixing 2 Styles |
ACS has an outstanding function of mixing music styles.
Let me explain this function. Suppose there are only 6
parameters such as "Music Scale", "Rhythm", "Tempo", "Harmony
Pattern", "Melody Instrument" and "Harmony Instrument" in ACS.
(Please note that following idea is applicable to processing by
ACS. This is not a story of musical styles in general.) |
|
With ACS, each parameters of
"Hard Rock" are defined as following. |
|
Musical Scale |
Diatonic Scale (Western Scale) |
|
Rhythm |
8 Beats |
|
Tempo |
120 bpm (Fast) |
|
Harmony Pattern |
Guitar Strokes |
|
Melody Instrument |
Vocal |
|
Harmony Instrument |
Distortion Guitar |
|
|
On the other hand, each parameters of "AOR (Adult Oriented
Rock)" are defined as following. |
|
Musical Scale |
Diatonic Scale |
|
Rhythm |
8 Beats |
|
Tempo |
80 bpm (Slow) |
|
Harmony Pattern |
Guitar Arpeggio |
|
Melody Instrument |
Vocal |
|
Harmony Instrument |
Acoustic Guitar |
|
|
Following process will be executed within the program in order
to mix "Hard Rock" with "AOR" and to create a new music style. |
|
1 |
Leave common part as it is. |
With the above example of
Hard Rock and AOR,
"Diatonic", "8 Beats", and "Vocal" will be left as it is. |
|
2 |
When there is variance,
and the value of the parameter continuously changes,
the value will be selected somewhere in the middle of 2
music styles. |
With the above example of
Hard Rock and AOR, "Tempo" is the value that
continuously changes. Therefore, value that is in between
"80" and "120" will be selected. For example, "90" or "110"
may be the one. |
|
3 |
When there is variance, and the value of the parameter
does not change continuously, the value that is either
one of the 2 music styles will be selected. |
With the above example of
Hard Rock and AOR, either one of "Guitar Strokes" or "
Guitar Arpeggio" will be selected as "Harmony Pattern" and
either one of "Distortion Guitar" or "Acoustic Guitar"
will be selected as "Harmony Instrument". |
|
|
For example, with above process, you will get a new music style
as follows. |
|
Musical Scale |
Diatonic Scale |
|
Rhythm |
8 Beats |
|
Tempo |
90 bpm |
|
Harmony Pattern |
Guitar Arpeggio |
|
Melody Instrument |
Vocal |
|
Harmony Instrument |
Distortion Guitar |
|
|
This new music style has a tempo
that is more slowly than that of Hard Rock and has soft
harmony pattern. If you compare this style with AOR, it has
faster tempo and punchy tones. |
|
|
|
|
Decomposition Of Music Style |
|
Let us consider and classify the
above mentioned process from broader point of view. As you can
see, Hard Rock and AOR are classified in hierarchic
structure as below. |
|
Music |
| Classic Music |
| Orchestra |
| Piano |
| Chamber Music |
|
|
Popular Music |
|
Rock |
|
AOR |
|
Hard Rock |
|
Heavy Metal |
| Ballad |
|
| Jazz |
|
| Fusion |
|
| Blues |
|
|
| Ethnic Music |
| Indian Music |
|
| Japanese Music |
|
| Indonesian
Music |
|
| Hawaiian Music |
|
|
|
|
|
As you can see from the above
list, both AOR and Hard Rock have characteristics of "Rock".
Since "Diatonic Scale", "8 Beats", and "Vocal" were common
parameter value within the 6 parameters such as "Musical
Scale", "Rhythm", "Tempo", "Harmony Pattern", "Melody
Instrument", and "Harmony Instrument", you can say that "Musical
Scale", "Rhythm", and "Melody Instrument" are the common
parameter of "Rock". |
|
Music style of AOR can be
decompose as follows: |
|
Music Style of
AOR = Common Parameters in Rock + Original Parameters of AOR |
|
Music style of Hard Rock can be
decompose as follows: |
|
Music Style of Hard Rock = Common
Parameters in Rock + Original Parameters of Hard Rock. |
|
If you go further in
decomposition, music style of AOR can be decomposed as follows:
|
|
Music Style of AOR = Common
parameters in Popular Music + Common Parameters in Rock +
Original Parameters of AOR |
|
For now, let us consider about
music style that is included in "Jazz". |
|
Followings might be a
little strong-arm approach to define music style of "Big Band",
but I would like to define the music style by following
parameters. |
|
Musical Scale |
Diatonic Scale |
|
Rhythm |
Shuffle |
|
Tempo |
90 bpm |
|
Harmony Pattern |
Guitar Strokes |
|
Melody Instrument |
Alto Sax |
|
Harmony Instrument |
Electric Guitar (without
distortion) |
|
|
Music style of Big Band can be
decompose as follows: |
|
Music Style of
Big Band = Common Parameters in Popular Music + Common
Parameters in Jazz + Original Parameters of Big Band |
|
"Diatonic Scale (Western Scale)" is common to AOR, Hard Rock,
and Big Band. Therefore, "Diatonic Scale (Western Scale)" is the
common parameter in Popular Music. |
|
If you sum up the relations of
parameters in the case of music style of AOR, they can be
described as below. |
|
Common Parameters in Popular
Music |
|
Musical Scale |
Diatonic Scale |
|
|
Common Parameters in Rock |
|
|
Original Parameters of AOR |
|
Tempo |
80 bpm |
|
Harmony Pattern |
Guitar
Arpeggio |
|
Melody Instrument |
Vocal |
|
Harmony Instrument |
Acoustic
Guitar |
|
|
|
|
|
|
Create New Style From Using 3 Styles |
|
As mentioned above, I have
explained about creating a new style by mixing 2 music styles.
This time, let us consider about creating a new style by using 3
music styles. |
|
ACS has 2 functions such as
"Import Common" and "Import Variance" that extract common part
or variance of 2 music styles and import to another music style. |
|
With "Import
Common" function that extracts common
part of 2 music styles and imports to another music style, the
following processing is executed to
3 music styles such as "A","
B", and "C". |
| 1 |
Extracts common part of style
"A" and style "B". |
| 2 |
Imports the extracted common
part into style "C". |
|
|
To be more specific, let us consider the above process with "AOR",
"Hard Rock", and "Big Band". |
| 1 |
Extracts common part of "AOR"
and "Hard Rock". |
"Diatonic Scale" , "8 Beats", and "Vocal" will be extracted. |
| 2 |
Imports the extracted common
part into music style of "Big Band". |
As a result,
you will get parameters such as "Diatonic Scale", "8 Beats",
"90 bpm", "Guitar Strokes", "Vocal", and "Electric Guitar". |
|
|
Musical Scale |
Diatonic Scale |
|
Rhythm |
8 Beats |
|
Tempo |
90 |
|
Harmony Pattern |
Guitar Strokes |
|
Melody Instrument |
Vocal |
|
Harmony Instrument |
Electric Guitar |
|
|
With above process, you will get
a new music style as follows: |
|
New Music
Style = Common Parameters in Popular Music + Common Parameters
in Rock + Original Parameters of Big Band |
|
The created parameters not
really stands out with the above example, but actually,
they make up interesting structure of "music style that
has common parameters in Rock with original parameters of Big
Band". |
|
Similarly, new music style can be created by extracting
different part of 2 music styles and import the extracted part
into the third music style. With "Import
Variance" function
that extracts different part of 2
music styles and imports to another music style, the following
processing is executed to 3
music styles such as "A","
B", and "C". |
| 1 |
Extracts different part of style "A" and style "B". |
| 2 |
Imports the extracted
variance into style "C". |
|
|
To be more specific, let us consider the above process with "AOR",
"Hard Rock", and "Big Band". |
| 1 |
Extracts different part of "AOR" and "Hard Rock". |
"80
bpm", "Guitar Arpeggio", "Acoustic Guitar" will be
extracted. |
| 2 |
Imports the extracted variance into music style of "Big
Band". |
As a result, you will get
parameters such as "Diatonic Scale", "Shuffle", "80 bpm",
"Guitar Arpeggio", "Alto Sax", and "Acoustic Guitar". |
|
|
Musical Scale |
Diatonic Scale |
|
Rhythm |
Shuffle |
|
Tempo |
80 |
|
Harmony Pattern |
Guitar Arpeggio |
|
Melody Instrument |
Alto Sax |
|
Harmony Instrument |
Acoustic Guitar |
|
|
With above process, you will get
a new music style as follows: |
|
New Music
Style = Common Parameters in Popular Music + Common Parameters
in Jazz + Original Parameters of AOR |
|
|
|
| Future
Possibilities |
|
Regarding Mix and Import
functions, I am thinking of upgrading them by allowing the users
to specify the amount of mixing and importing by percentage. |
