Harmonic Highlights:

  • The progression features a chromatic ii-V (Ebm7 - Ab7) that acts as a tritone substitute for the secondary dominant (D7), smoothly leading into the supertonic Dm7.
  • Secondary ii-V patterns (Gm7 - C7) are utilized to tonicize the subdominant Fmaj7, providing brief modal shifts within a diatonic framework.
  • The turnaround utilizes a chromatic descending line (A7 - Ab7 - G7), where Ab7 serves as a tritone substitution for D7, creating a sophisticated resolution to the tonic Cmaj7.

Improvisation Focus: Guide tone navigation, focusing on the resolution of 7ths to 3rds during the chromatic ii-V transitions.

Difficulty Rating: 2/5. The tune is largely diatonic and follows a predictable AABA structure, making it accessible for developing players to practice chromatic substitutions.
