Random 4

8 minutes of sound game with randomness. 2 scales of 6 notes are generated with a random function. For each scale 10 different patterns of 6 notes are created. The composition for piano alternates the motifs of one scale then the other. For each range the order of the patterns is random but a rule of succession rejects certain combinations. Finally there are only 15 models used. The compositions of the other instruments are generated with algorithmic rules from the notes of the pianos.
