In this part 2 about the 6th diminished theory where Jazz legend Barry Harris became famous for, we look at the theoretical side of it (practical applications you’ll find in part 1). The theory is about connecting 24 chords by means of 4 scales. The harmonization of the 6th diminished scales can be used for comping or substituting chords.
This tutorial provides a easy to understand and crystal clear explanation of this complex subject.
