Harmonic Highlights:

  • The Db07 chord functions as a chromatic passing diminished (bIIIdim7), creating tension before resolving smoothly into the Cm7 (ii7) chord.
  • Frequent ii-V-I progressions (Cm7-F7-Bbmaj7) consistently reinforce the song’s Bb major tonic key.
  • A secondary dominant, C7 (V7/V), temporarily tonicizes the F7 (V) chord, adding forward motion and a brief harmonic departure.
  • The Dm7-Gm7 (iii-vi) progression offers a classic diatonic movement, setting up subsequent sections.

Improvisation Focus: Chord tone outlining and strategic chromaticism, especially over the diminished and secondary dominant chords.

Difficulty Rating: 3 (Intermediate). While many progressions are standard ii-V-I, the specific diminished chord and secondary dominant require thoughtful harmonic navigation.
