Harmonic Highlights

  • Utilizes a “Backdoor” progression (Abm7–Db7) resolving to Ebmaj7, blending subdominant minor flavor with chromatic leading tones.
  • Frequent use of secondary dominants (C7–F7–Bb7) creates a strong cycle of fifths momentum leading back to the tonic.
  • The bridge modulates to the relative minor (G minor) via a ii-V-i (Am7b5–D7–Gm7), providing significant tonal contrast from the major-key A sections.

Improvisation Focus Eb Major Bebop scale, emphasizing chord tone transitions through the secondary dominants and the backdoor ii-V.

Difficulty Rating 3/5: While the A section is standard, the bridge’s modulation and the rapid sequence of secondary dominants require a solid understanding of functional harmony.
