This new, revised edition emphasises the practical and is even more useful to beg.
Also, it presents usable groups of chords for beginners in relation to a variety of song styles.
Rather than just show Chord shapes which are all there in the Chord Matrix a large portion of the book explains how to use chords, with information about the theory behind them, and attempts to answer the questions guitarists often have about Chord shapes.
Chord Master is a Chord dictionary with a difference. (Book)
