Harmonic Highlights:

  • Classic tonic prolongation is established using Eb, Eb6, and Ebmaj7, showcasing subtle internal movement within the I chord.
  • A concise iiø7-V7b9-i progression (Dm7b5-G7b9-Cm7) effectively tonicizes the relative minor (Cm).
  • The B7#11 functions as a chromatic dominant, specifically a tritone substitution for F7 (V/Bb), creating advanced tension before resolving to the primary dominant, Bb7.

Improvisation Focus: Navigating ii-V-I progressions, including the temporary tonicization of the relative minor.

Difficulty Rating: 3 (Intermediate) - The core harmony is accessible, but the chromatic dominant substitution (B7#11) requires a deeper understanding of dominant function and altered scales.
