 - [ ] Chords should be composed of Notes, not ordinary arrays
 - [ ] There should be a Musical_Phrase object that holds phrases (and sets of
   phrases), and allows them to nest
 - [ ] Does each instrument need a score parameter if the grammars are non-terminating?

 - [ ] Generate score with proper generation tools, not this string-replace nonsense
 - [X] Store csound score lines with instruments
 - [ ] Upgrade from simple string substitution for the score to something
   list-based (maybe). Idea is to keep musical phrases intact in the event of a
   truncation of the score. Also, if done right, no need for retroactive length
   parsing- a measure is has a specific length, which is known at
   generation-time, thus solving the length limit problem.
