Harmonic Highlights:

  • The opening Em7b5-A7b9-Dm7 provides an immediate, reharmonized ii-V-i progression in D minor within the F major tonic.
  • Features a rapid succession of ii-V-I sequences, frequently modulating to non-diatonic keys (e.g., Cm7-F7-Bb7, Bbm7-Eb7).
  • Prominent use of tritone substitutions, such as Db7 for G7, creates chromatic tension and unexpected resolutions.

Improvisation Focus: Precise chord-tone outlining and scale application across the dense, rapidly changing ii-V-I progressions.

Difficulty Rating: 5 (Advanced) due to the high harmonic rhythm and frequent non-diatonic modulations demanding intricate melodic navigation.
