Looks like Fancy Pants has a new companion.
Very nice art, unique control scheme (though I would've liked to be able to move my mouse off the window instead of it being stuck in the center).
I could see this being a fleshed-out game. Maybe add power-up where he turns into a white hole for a split second, and repels the notes (or one of his other cousins is a white hole and comes to the rescue).
I love the small details (head changes sizes based on the music, the cousins).
