Harmonic Highlights:

  • Stepwise bass movement via inversions (Ebmaj7/Bb to Eb6/G) facilitates smooth voice leading across the tonic expansion.
  • The B7 chord acts as a chromatic approach or tritone substitute for F7, adding non-diatonic tension to the Eb major center.
  • A secondary minor ii-V sequence (Gm7b5 - C7b9) introduces temporary tonicization of the supertonic (Fm7), shifting the tonal color.
  • The C#o7 (#iio7) functions as a chromatic passing chord, bridging the movement between the vi chord and the dominant.

Improvisation Focus: Eb Major scale with emphasis on the b9 and b13 tensions over the C7b9 to highlight the transition to the minor ii.

Difficulty Rating: 2. The predictable waltz structure and strong diatonic foundation are beginner-friendly, requiring only basic navigation of secondary dominants and passing diminished chords.
