Harmonic System Introduction
The harmony of popular music and jazz is based on the diatonic or major scale. Each of the twelve scales is a frame forming the harmonic system. Diatonic harmony moves in two directions: Horizontal and Vertical. By combining these these two movements using the root, third, fifth, and seventh, we derive the scale-tone seventh chords. You will be exposed to the seven diatonic seventh chords in all twelve key in addition to examining the qualities of each scale degree.
