>> Hi Lisa
>> This is Pete Clemmer, '09, the guy you kindly met with about the music
>> program.  Here's a little explanation of what's up with my program, with
>> code attached.  If you can find someone(s) who might help me, that would be
>> super awesome.  In any case thank you very much.
>> best :),

>> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
>> so i'm trying to write a program that generates a list of all chord
>> progressions, ranked by how well they fit with some Bach-style rules of
>> counterpoint, from user input that gives specification about what kind of
>> chord progression is desired.  the idea is to use this to write
>> smoother/more interesting sounding orchestration.
>> 
>> my basic set up is that the program takes in and generates some notes as
>> numbers and then puts them into progressively more
>> combined/ordered/permutated data structures until there's a data structure
>> containing ranked chord progressions.
>> 
>> data structure 1 is made of objects called Struc1bignodes, each containing
>> all the potential notes for each part (clarinet, violin, etc.) for one
>> chord.
>> 
>> my problem is that i want the notes from each Struc1bignode to be rearranged
>> and stored as all possible chords in an object called a versionsofachord, so
>> there'd be a versions of a chord for each Struc1bignode.  for example,
>> 
>> HARMONY 1:
>> Part 1:
>> notes:  33,45,57,69,81,93.
>> Part 2:
>> notes:  35,47,59,71,83,95.
>> Part 3:
>> notes:  24,36,48,60,72,84,96.
