Product questions
Straight answers to the questions shoppers most often ask about this product.
Basic note reading helps considerably. The material is organized around scales, chords and note relationships, so some prior grounding in theory makes it far more usable.
No. It is a theory reference covering scales, chords and progressions. A beginner wanting to learn to play should start with a graded method book instead.
Yes. It is written for guitarists as well as keyboardists, and seeing theory on a keyboard layout often clarifies intervals that fretboard shapes obscure.
No. It is a printed book only, with no audio tracks, backing tracks or online component.
