Over the past few months I have been co-developing a phone app with Leafcutter Studios. The idea is that the app teaches the CAGED system for learning the guitar fretboard. If you've not heard of it, the CAGED system takes five basic chord shapes and orientates everything from there – it really does accelerate your learning; I was introduced to it by the legendary jazz guitarist Joe Pass way back at the beginning of the 1980s and it increased my knowledge of the fretboard almost instantly.
We've employed some games in the app that test your fretboard knowledge in a fun way and we've even included a facility to view the fretboard diagrams in a left-handed configuration!
The app is available for both Android and iPhone users and costs $1.99.
