I had to write an aleatoric piece of music for an assignment and this is what I came up with. I started with some prepared information such as the tempo/ length and instrumentation just to make my life a little bit easier. Then I came up with a system of numbers to represent the dynamics, pedaling, articulation and notes in the piece.
Then, by asking random people on reddit and facebook to choose numbers between a set of ranges, I used those answers to notate this piece of music. It took 40 people in all to generate this 1:30 of music.
It came out interestingly (especially the octave playing together somehow) but I absolutely know what I would have changed if I were to do this all again.
