OK, here is yet another musical representation method that you may find interesting (especially if you have a modern bent):

Take a tune, and now arrange some graph paper like the "note pattern view" in a sequencer, with one difference. Instead of arranging the pitches in the normal way, arrange them by the order they come in the tune. (so the first note of the tune will be the "lowest" pitch, second note the second "lowest" and so on.

You might see some interesting things that you didn't hear!

Probably Mozart would be a good target to do this with, and pop music would not, but I could be wrong on that. Possibly this is over your head, but possibly not.

Then if you want to add a ton more formalism, read a little about serialism, and apply this technique to a twelve tone piece. You will be rewarded for your efforts, as a previously difficult to follow piece makes much more sense. Doesn't mean you'll find it pleasing to listen to though.
