Jon - I believe there are a couple of "Optical Music Recognition" programs available, but I haven't looked into them because they cost well over a hundred bucks - and I'd also have to invest in a flatbed scanner to read my songbooks. I'm on the prowl for one, though. I don't read music very well and I've failed at playing every instrument I've attempted. I have lots of great songbooks, but the only way I can teach myself a song is to enter it into Noteworthy, which is a tedious process.
