Play with permutations

[evanlenz]

This is an extension to the piece-reconstruction algorithm.

Permutations can include:

• the same eight notes (per half-measure) in different orders
• permutations of a different selection of eight from the same five (i.e. with a bass note or two being played twice instead of all the treble notes being played twice)

Answer this math problem: how many possible permutations are we talking about here?

If it’s not overwhelming (i.e. doesn’t take hours to hear them all), generate and listen to them all.

[evanlenz]

Possible constraints if we want to or need to limit the number of permutations:

• Don’t repeat the first two notes of each half-measure
• Don’t repeat notes consecutively (e.g. G in G G C E C E)
