FiddlewidgetTM: Roadmaps for your Instrument

1. Beginners, intermediate level players, and even advanced musicians love this thing. Locates all possible major chords anywhere on the neck, and  teaches converting to other chord forms
2. It does what big, comprehensive chord books will do, but is much more convenient, compact and will find your chords all over the neck.
3. Encourages and helps the student to learn the fingerboard, which is what teachers want.
4. It also will teach you some simple, applied music theory without your even realizing it.
5. You can use it to find your chords and scales, calculate where to capo, transpose from one key to another, anything that has a basis in scale theory.
6. But you do not need to know anything about theory to begin using it.
