Harmonic Highlights

  • The Db07 chord functions as a chromatic passing diminished, creating tension before resolving to the Cm7.
  • A classic ii-V-I progression (Cm7-F7-Bbmaj7) forms the essential harmonic movement.
  • The F7#5 is an altered dominant, providing a strong, colorful resolution to the tonic Bbmaj7.

Improvisation Focus Navigating altered dominant chords (e.g., F7#5) is paramount.

Difficulty Rating 3 - Intermediate. While featuring a clear ii-V-I structure, the chromatic diminished chord and altered dominant require an understanding of non-diatonic and tension-release harmony.
