Great way to learn to play guitar.

This app really helps you when you are learning to play guitar. The notes of the song and their chord shapes scroll by and you follow along and before you know it you have got some decent practice time on your instrument. I spend an hour or so a day and it really breaks the drudgery of practicing pentatonic scales and modes.
