Harmonic Highlights
- The progression frequently features a classic II-V-I (Bb7-Eb7-Abmaj7) firmly establishing Ab major as the key center.
- A notable chromatic tension is introduced by the B07 chord, acting as a non-diatonic diminished sonority before resolving to the Bbm7 (II minor).
- The use of F7-Bb7-Eb7 creates a strong dominant chain (V/V/V to V/V to V) efficiently returning to the tonic area.
- The C7-Fm6 section provides a clear V-i temporary tonicization of the relative minor (Fm).
Improvisation Focus Navigating II-V-I progressions and dominant cycles.
Difficulty Rating 3 (Intermediate) – The foundational II-V-I movements are clear, but the chromatic diminished chord and temporary tonicizations demand attentive melodic and harmonic navigation.
