Harmonic Highlights

  • The A-sections utilize a foundational I-IV-V progression (Eb-Ab-Bb7) typical of early 20th-century pop-jazz, emphasizing strong subdominant-to-tonic resolutions.
  • The bridge features a secondary dominant pivot (D7b9) leading to Gm, functioning as a momentary V/vi to create harmonic tension.
  • A modulation to G Major occurs in the bridge via a ii-รธ-V-I sequence (Am7b5-D7-G), representing a shift to the parallel major of the relative minor.
  • Frequent use of the I7 (Eb7) functions as a secondary dominant (V/IV), bridging the gap between the tonic and the subdominant Ab major.

Improvisation Focus Eb Major Pentatonic/Blues scale hybrid for the A-sections, shifting to G Harmonic Minor over the bridge’s D7b9.

Difficulty Rating 2/5: The primary structure is highly diatonic and repetitive, though the bridge requires navigating a brief modulation to G.
