Query: Review for Contemporary Music Theory level 1- Mark Harrison

Mark takes you through chapters on notation, major and minor scales, intervals, triads and four-part chords, modal scales and diatonic relationships. A VERY detailed and well explained book w/ great examples on what a certain topic is about. A must for anyone who's just starting to get into music theory. Might want to also consider Contemporary Music Theory level 2, also by Mark Harrison once you're well versed in Level 1.
