- The opening Am, Am/maj7, Am7, Am6 progression showcases a sophisticated minor line cliché over a non-diatonic starting chord (A minor in F minor), establishing a unique melancholic mood.
- A strong iiø7-V7b9-i progression (Em7b5, A7b9, Dm7) firmly tonicizes D minor, the relative minor of F major, demonstrating a clear temporary modulation.
- The Db7#11 chord functions as a Lydian Dominant tritone substitution (for G7), resolving chromatically to Abmaj7 (the relative major of F minor), indicating advanced harmonic substitution.
- The D#07 chord serves as a chromatic diminished passing chord, creating tension and leading uniquely to Dm7, adding a layer of sophisticated voice leading.
Improvisation Focus: Navigating transient tonicizations and altered dominants with appropriate chord-scale choices.
Difficulty Rating: 4 (Advanced Intermediate). The frequent modulations, altered dominant chords, and diminished chord usage demand a strong grasp of advanced harmonic concepts and chord-scale applications.
