Harmonic Highlights:

  • The prominent Bb7 (bVII7) resolving to Cmaj7 (Imaj7) establishes a classic “backdoor dominant” cadence.
  • Frequent D7 (V7/V) leading to G7 (V7) reinforces traditional functional harmony and dominant preparation.
  • A temporary ii-V-I in F (Gm7-C7-F6) briefly tonicizes the subdominant, adding harmonic color.
  • The E7 (V7/vi) introduces a standard secondary dominant, setting up motion towards the relative minor.

Improvisation Focus: Major and Mixolydian scales, adjusting for secondary dominants and the bVII7 chord.

Difficulty Rating: 3 (Intermediate) - The tune combines diatonic harmony with common secondary dominants and the jazz-specific backdoor cadence, requiring moderate scale adjustments.
