My wife plays the piano, and when we hear a good kids song, she likes to find the sheet music so that she can play it for our kids. The other night my sisters were singing the “Arky, Arky” song that Rod and Todd sing on The Simpsons (“God said to Noah, there’s going to be a floody, floody”). I could find a midi file of the music, but couldn’t find any free copies of the sheet music. I stumbled across Notation Software, Inc. They have software called MidiNotate Musician that, among other things, will open a MIDI file and display it as sheet music. Nice!
