Harmonic Highlights:
- Prominent use of the Eb7 (bIV7) chord, injecting a bluesy dominant color before resolving to the Bb tonic.
- Standard ii-V-I progressions (Cm7-F7-Bb6) firmly establish the Bb major key center.
- Incorporation of secondary dominant functions with ii-V sequences (Fm7-Bb7 to Eb) and V/V (C7) adding harmonic movement.
- The B07 chord acts as a passing diminished, often functioning as a substitute for G7b9 (V7/ii), leading to Cm7.
Improvisation Focus: Arpeggio outlining and guide-tone improvisation over the ii-V-I and secondary dominant progressions.
Difficulty Rating: 3 (Intermediate) - The tune features standard ii-V-I changes augmented by secondary dominants, a passing diminished, and blues-inflected harmony, requiring solid harmonic navigation.
