Harmonic Highlights:
- Establishes the subdominant key (F major) early with a ii-V-I progression (
Dm7, Gm7, Fmaj7). - Features a sequential chain of secondary dominants, specifically V/V/vi followed by V/vi leading to the tonic minor (
B7, E7, Am). - Incorporates a distinct minor ii-V-i progression, tonicizing D minor (
Em7b5, A7, Dm7). - Includes modal interchange with chords like
Bbmaj7(bVII) andF7(bVII of G or V/Bb).
Improvisation Focus: Navigating temporary tonicizations and secondary dominant resolutions using a chord-scale approach.
Difficulty Rating: 4 (Advanced Intermediate) The frequent temporary modulations and use of non-diatonic chords demand a solid understanding of harmony beyond basic diatonic playing.
