A chord might consist of 3
or 4 notes. For example, C major chord consists of notes C, E, G.
If you select these notes by using random numbers, then they might be C,
C#, D. These notes are disonance and can not be called chord. So, you can
not select notes randomly when you make chord. There must be some rules
to construct a chord. |
Assign numbers to 12 notes,
from C to B. 1 to C, 2 to C#, 3 to D, 4 to D#, and so on. |
Categorize these notes into
4 groups.
|
Get a number from 12 face
dice. If the number is 5, make a sound of E. Get a number from the dice
again. If the number is 1, make a sound of C. So, it makes a harmony with
C. However, if a note which belongs to the same category of prior note,
then stop the sound of prior note and begin the new sound. For example,
if you get 4, then stop the E sound and begin the D# sound. |
For example, if you get the
numbers as 1,5,8,7, then you get a score like this.
|
If you get the following numbers
as 2, 10, 10, 12,
then the score will be like this.
|
Chords which consist of 4
notes are keeping generated if you continue this process. |
