Aleatoric Music

Aleatoric is music in which some element of the composition is left to chance.

1) Choose six notes from the piano. 
 

2) Then give each note a number.

​

3) Roll a dice any number of times to create a row of notes (tone row).

Here's an example of what might happen...

C = 1      F = 2     G = 3     G# = 4     A = 5     A# = 6

​

I've rolled the dice 5 time and had these numbers

3 then 4 then 2 then 2 then 6

G         G#        F          F          A#   (my tone row)

​

Then I can make a melody with those notes!
