FEATURES:

CHORDS
Explore a library of more than 7,000 guitar chords by simply tapping and strumming the touch screen. View chords in every position up and down the guitar neck and hear each one played back in pristine audio. There's even a "lefty" mode for the oft-neglected southpaw.

SCALES
Improve your technique by choosing from thousands of scales, modes and arpeggios to practice. Try multiple positions and alternate tunings to boost your versatility. Use "big stretches" for unique, challenging fingerings.
