Riffstation (Acquired by Fender)

Riffstation automatically calculates the chords for any song in the world and shows you how to play them in sync with the original music. If you are not a guitar player we can show you piano and ukulele chords too. The pro version lets you slow down guitar solos and loop tricky riffs. You can even take the guitar player out of the mix and create your own backing tracks. Beginner or Pro, Riffstation has got all the tools you need for learning your favorite songs.
