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!
