Harmonic Highlights

  • The opening I-V7sus movement (Ebmaj7-Bb7sus) establishes a lyrical quality by softening the dominant-to-tonic resolution and delaying the leading tone.
  • A iii-VI-ii-V sequence (Gm7-C7-Fm7-Bb7) utilizes the secondary dominant C7 to create a strong pull toward the supertonic (Fm7).
  • The progression incorporates a V7/IV (Eb7 to Ab7), introducing Mixolydian color and a blues-inflected transition to the subdominant.
  • A definitive modulation to the dominant key (Bb major) occurs via a ii-V-I (Cm7-F7-Bbmaj7), providing the necessary tonal contrast for the bridge.

Improvisation Focus Navigating sequential ii-V-I progressions and targeting the 3rds and 7ths to define the shifting harmonic centers.

Difficulty Rating 2/5: The piece relies on standard functional harmony and predictable jazz cadences, making it highly accessible for intermediate improvisers.
