How AI describes The Chord Wheel

Chord Wheel is a musical theory tool and book that helps songwriters understand key structure and master chord theory while enabling instant transposition of chord progressions into any key. It exists as a physical wheel (and accompanying book) and as an iPhone app that lets users interact with chord cells and hear each chord played in piano or guitar with various voicings. Created by Jim Fleser and marketed as a best-selling educational resource, it has ties to Hal Leonard Publishing and aims to simplify learning, composing, and improvising with chords.
