If I don't already have it mapped out or given to me beforehand I just make them what I want. The number just comes out to whatever it happens to come out to. I don't do this stuff with a view to make everything 5,000 permutations or 10 permutations or a million permutations.So what are the constraints when working it out to that number? Is it the intervals? 2nds? 3rds, 4ths? Is it the order of pitches? Ascending? Descending? Alternating? Up 3 down 2? Is it the time values of each note? All whole? Half? Quavers and 2 semiquavers? All combinations of 16th subdivision? Crotchet triplets? And what is the ambitus? 2 octaves? 3?
