I need help for this program

I want to build an algorithm that generates random (music) scales based on the fact that we have 12 semitones and only 2 possible steps (semitone, wholetone). I thought I should create a list with a variable number of indexes, the sum of them has to be 12 everytime and the only acceptable values are 1 and 2 (semitone, wholetone). However I can't figure out how to translate this logic into java code, anyone can help?

I don't understand your logic: 1) Distances between successive notes can be any length 2) Why would the sum of indexes equal 12?

I'll explain myself better: Im not talking about generating a "solo" of notes, I'm talking about creating the structure of a scale, lets take the typical diatonic major scale structure (x=root note, T=whole step, t=half step): x-T-T-t-T-T-T-t now lets assign T as 2, and t as 1... is it clear now? Another example: the Debussy scale, only composed by whole steps, that'd be: 2-2-2-2-2-2 This algorithm could supppsedly generate any diatonic or modal scale plus the artificial ones, like the Debussy's or the chromatic which is only made of half steps.

Right, that does make sense now! I'll look into this. Maybe someone else will beat me to it though.
