This might depend on your personal preference and approach, but I like books with high information density, with pieces that I can chew on for a long time - even if much of it is beyond my understanding at the beginning (or even at the end). Here are some of my favorites: The Jazz Theory Book (Mark Levine) Huge series of play-along books by Jamey Aebersold The Geometry of Musical Rhythm (Godfried Toussaint) Harmony (Walter Piston) A Geometry of Music - Harmony and Counterpoint in the Extended Common Practice (Dmitri Tymoczko) Lydian Chromatic Concept of Tonal Organization (George Russell) Augmented Scale Theory (Javier Arau)
