Capo 2.0

Capo is a revolutionary tool that helps you learn the music in your iTunes library. By slowing your music, and presenting a detailed spectrogram, Capo lets you hear and see your music like never before.

No longer do you have to rely on the musical tastes of others to learn music. Drag songs right from your music collection into Capo to start learning them.
Figure out the chords in your music using Capo's sophisticated chord detection routines. Or, enter your own easily using strings like ‘bbmaj7’ or ‘f#maj9’.
Capo lets you adjust the pitch of your songs—so you can change their key or fine tune them to match your instrument.
By simply drawing atop the spectrogram, Capo will generate tablature automatically for you. It really doesn't get much easier than this!
