Harmonic Highlights

  • The piece utilizes an A minor line cliché (Am-Am/maj7-Am7), creating internal chromatic voice-leading within the relative minor.
  • Frequent modal interchange occurs through chords like Ebmaj7 and Abmaj7, briefly shifting the tonality toward the parallel C minor.
  • The progression employs “backdoor” dominant resolutions (Bb9sus to C), substituting the standard V-I cadence with a bVII-I movement.
  • Non-functional harmonic shifts, such as D/F# to F, provide smooth bass transitions while subverting traditional diatonic expectations.

Improvisation Focus Navigating Modal Interchange by blending C Major with C Aeolian (Parallel Minor) scales.

Difficulty Rating 3/5: While the key center is stable, the frequent excursions into flat-key modal interchange require intermediate harmonic navigation skills.
