I think Clairnote is pretty neat. There are more alternate musical notation systems at http://musicnotation.org.

The current system we use because it is the one experts know and music is written in. I'm sure it could be worse, but I feel like it has a ton of backwards-compatible features as add-ons that would be so much cleaner with a rewrite. The very simplest change that could be made would be to have a grand staff that uses the same clef, so people don't need to learn two of them.

I don't think we'll actually see a change until such time as you could put on a pair of AR glasses, which could recognize/OCR your music, and then, on-the-fly 'transnotate' the song into a sane notation. (Perhaps the same could be said for making English more phonetic; and, perhaps it will never happen; in the meantime, I can't help but feeling that hundreds of hours are needlessly spent learning this system that wouldn't be needed with a simpler one, many people who'd like to learn it never do, and, oddly, plenty of singers sing better because they can't read the written notation!).
