Harmonic Highlights

  • Employs a back-door dominant resolution (IV6 - bVII7 - Imaj7), utilizing the Bb7 to provide a subdominant minor flavor before returning to the tonic.
  • Integrates secondary dominants (II7 - V7), where D7 functions as a V/V to strengthen the primary G7 dominant cadence.
  • Includes a ii-V-I tonicization of the IV chord (Gm7 - C7 - F6), briefly shifting the tonal center to the subdominant.
  • The bridge utilizes V/vi secondary dominants (E7), typically resolving toward A minor or cycling back through the circle of fifths to reach the tonic.

Improvisation Focus Guide Tone Mapping to navigate the transitions between the diatonic major scale and the non-diatonic tones of the bVII7 and II7 chords.

Difficulty Rating 2/5. The predictable 32-bar AABA structure and standard functional progressions make it an accessible entry point for learning swing-era vocabulary.
