In Harmony, you will focus on learning chords and how to play them in any inversion anywhere on the instrument. The Beginner section focuses on different accompaniment styles over one specific chord progression (Am, G, Em, F). In the Intermediate section, the exercises cover many different chord patterns that you can use to learn chords in all inversions as well as sus chords. The exercises in the Advanced section focus on jazz extensions such as 9ths and 13ths.
