- Frequent use of II-V-I progressions in both the tonic (Fm7-Bb7-Ebmaj7) and subdominant (Bbm7-Eb7-Abmaj7) keys.
- Incorporation of a backdoor dominant via tritone substitution (Db7 resolving to Ebmaj7).
- Secondary dominant function is evident with C7b9 leading to Fm7 (V7/ii to ii).
- The A07 (fully diminished) chord acts as a common tone diminished, sharing Eb with the target tonic, creating a subtle chromatic resolution.
Improvisation Focus: Arpeggios and Chord Tones.
Difficulty Rating: 3 (Intermediate). Features standard II-V-I progressions, but includes tritone substitutions and a common tone diminished chord, requiring moderate harmonic understanding.
