Ever wondered what the key of a song being played is? Wonder no more! Just use the built-in piano keyboard to play along with a song's melody. As you confirm notes that coincide with what's being played, KeyFinder will narrow down the number of possible keys the song is in.

Do check out the Scoreless Music Forum for more tips on how to use KeyFinder.
