Harmonic Highlights:

  • Prominent use of the IV7 chord (Ab7) resolving to the I (Ebmaj7), introducing a bluesy, subdominant dominant color to the major tonic.
  • A sequence of implied secondary dominants (C7 as V7/F, F7 as V7/Bb) creates driving harmonic motion through temporary tonicizations.
  • Frequent non-diatonic dominant 7th chords (Ab7, C7, F7) provide rich harmonic tension and chromaticism characteristic of stride and swing styles.

Improvisation Focus: Mixolydian scales over the various dominant 7th chords.

Difficulty Rating: 3 (Intermediate). The tune features non-diatonic dominant chords and quick harmonic rhythm in places, requiring a solid grasp of functional harmony and dominant scale application.
