Harmonic Highlights
- Prolonged tonic minor (Gm) establishes a strong modal center before introducing harmonic movement.
- A unique oscillation between C7 (V7/F or secondary dominant to iv) and Cm7 (iv7) creates harmonic tension over a static root.
- This C7-Cm7 progression avoids a typical ii-V-i resolution, challenging standard functional harmony expectations.
Improvisation Focus Emphasizing chord quality changes, particularly distinguishing between C7 (Mixolydian/Altered) and Cm7 (Dorian/Aeolian).
Difficulty Rating 3 (Intermediate). The extended tonic minor is approachable, but the rapid alternation between dominant and minor qualities on C requires careful outlining.
