Harmonic Highlights:
- Frequent use of secondary dominants, notably C7b9 (V/Fm) and G7 (V/Cm), adding tension and clear temporary resolutions.
- Includes a tritone substitution with Gb7 resolving to Fm7 (bVI7 to ii), implying substitution for C7.
- Features a blues-inflected Ab7 (IV7) instead of a diatonic Abmaj7, injecting a dominant quality into the subdominant.
- Strong foundation in ii-V-I progressions, particularly Fm7-Bb7-Ebmaj7, anchoring the harmony in Eb major.
Improvisation Focus: Chord-scale theory application over ii-V-I progressions.
Difficulty Rating: 3 (Intermediate) - The tune is primarily diatonic with common ii-V-I changes, but features strategic secondary dominants and a tritone substitution requiring specific harmonic navigation.
