Harmonic Highlights
- Prominent use of secondary dominant chains, notably D7-G7 (V/V/ii to V/ii) and C7-F7 (V/V to V), driving the progression towards the tonic.
- The Ab7 (bVII7) functions as a backdoor dominant resolving to the Bb major tonic.
- Chromatic interest is generated by the Fm7 (non-diatonic ii of Eb) and the E07 passing diminished chord.
Improvisation Focus Mixolydian scales and altered dominant concepts over the numerous V7 chords.
Difficulty Rating 3 (Intermediate) - The frequent secondary dominants and chromatic alterations require understanding harmony beyond basic diatonic progressions.
