It actually sounds like your representation has structure, but you dislike structure because it's hard to work with.

It seems to me like the data has structure, but that data is not treelike! Is a performance a collection of measures or a collection of instruments? A tree-like structure makes you choose, but in truth it is both. I'm not sure I've seen a good solution to this kind of problem in FP. --Max
