Harmonic Highlights:

  • The prominent use of IV7#11 (C7#11) and bVII7#11 (F7#11) introduces a distinctive Lydian Dominant sound, adding sophisticated color and tension.
  • Standard ii-V-I progressions are clearly featured, such as Bm7-E7b9 resolving towards Am7, establishing foundational jazz movement.
  • The Bbø7 functions as a chromatic passing diminished chord, providing smooth voice leading between Bm7 and Am7.
  • The concluding Dm7-G7 sequence serves as a classic jazz turnaround, frequently setting up a return to the tonic or a temporary resolution to C major.

Improvisation Focus: Lydian Dominant scale.

Difficulty Rating: 4 (Advanced Intermediate) The frequent #11 chords and chromatic diminished harmony require careful melodic navigation beyond basic diatonic thinking.
