This extensively revised third edition of David Harp's best-selling Music Theory Made Easy is an easy to follow treatment of a difficult subject. Without requiring the reader to know standard notation, the guide uses pictures, diagrams, and simple analogies to cover all the theory topics involved in playing – and understanding – blues, rock, country, pop, and simple jazz music. The 74 minute CD lets you hear what each scale, chord, and chord progression sounds like, and provides play-along tracks in commonly used keys for each style of music.
