In case anyone is interested, I played around with a novel musical notation paradigm in the form of an iPad app a few years ago: http://composerssketchpad.com http://composerssketchpad.com (I don't think it works anymore, and I don't have the ability to update it at the moment due to work conflicts. Also, sorry for the crappy trailers: I barely knew what I was doing back then!) Basically, you draw pitches directly on a horizontally-infinite canvas. By default, pitches stick to equal temperament gridlines, but you can turn off this snapping if you want to play around with a microtonal tuning or annotate a bendy guitar solo. The intent was to create a notation system that's intuitively usable and (theoretically) able to represent any pitch-based music. I wanted to add the ability to specify arbitrary snapping grids as a v1.1 feature, but I ran out of time. Will come back to it someday; hope to move it to a more universal platform and add power user functionality that would take it out of the "toy" category and turn it into an actually useful compositional tool. Also, this was before MIDI 2.0, so arbitrary per-note pitch bending was implemented as a huge hack — definitely looking forward to that refactor. None of this is intended for sight reading, though. It's more about being able to jot down completely arbitrary pitches with relative ease.
