Harmonic Highlights
- Standard II-V-I progressions are consistently employed to establish and return to the F major tonic.
- The recurring Ab07 functions as a common diminished chord, creating chromatic tension and smooth voice leading into the Gm7-C7-Fmaj7 progression.
- A clear modulation to the subdominant (Bb major) is achieved through a ii-V-I (Cm7-F7-Bb6) movement.
- Secondary dominant G7 (V/V) is utilized to prepare the return to the main II-V-I in F.
Improvisation Focus Mastering II-V-I navigation, including modulations and understanding the chromatic tension provided by the diminished chord.
Difficulty Rating 3 (Intermediate). The standard II-V-I movements and modulation are accessible, but the specific diminished chord usage requires harmonic awareness.
