These books have extensive exercise sections with answers provided, and are great for all instrumentalists, writers and arrangers.

Please watch the video on this page, where Mark Harrison explains more about our Music Theory products and how they can help you. If you would like to focus on a particular volume in the series, the video start times for each book are: Level One 0:47, Level Two 5:21, and Level Three 9:32.
Level One is ideal for beginners and covers notation, major and minor scales, key signatures, triads and 4-part chords, diatonic chords and alterations.
Level Two covers the chords and substitutions used in jazz and pop styles (with many progression examples from well-known songs) as well as voice leading, "upper structure" voicings and blues & pentatonic scale applications.
Level Three covers all commonly used chords including extensions and alterations, scale sources, melody harmonization, polychords and advanced voicings using our "contemporary shape concept". Audio recordings are also available with the Level Three book.

All Contemporary Music Theory books and audio material created by Mark Harrison. (Please note there we only have audio recordings available with the Level Three book - not the Levels One or Two books).
