Harmonic Highlights

  • Frequent Fm7 (v7) in Bb major establishes a distinct minor dominant color, contributing to a melancholic modal flavor.
  • Strong secondary dominant progressions are evident, notably D7b9 to Gm7 (V7b9/vi) and C7 (V7/V) implying a resolution to F.
  • Bb7 functions as a secondary dominant to Ebmaj7 (V7/IV), driving harmonic motion within the subdominant area.
  • The Ab major triad (bVII) introduces a modal interchange moment, briefly expanding the harmonic palette.

Improvisation Focus Precise application of modal scales (Dorian for minor 7ths, Mixolydian for V7s) to effectively outline the fluctuating chord qualities.

Difficulty Rating 3 (Intermediate) โ€“ Requires careful navigation of frequent secondary dominants and distinct modal interchange chords like Fm7 (v7).
