covers the basics, how to read notes on the staff, intervals, major and minor scales, key signatures, triads, inversions, basic rhythms and song forms, chord charts and lead sheets. Designed for complete beginners regardless of instrument. It's the same text I use in my Basic Musicianship courses. If you're looking to prep for a jazz/commercial college program and have no experience in music theory this will get you on the right track. All explanations are simple and to the point. Also great for anyone looking to understand the basics.
