Harmonic Highlights
- Recurring Am7-D7 progression functions as a ii-V in G major, often resolving deceptively back to Am7, creating a ‘minor ii-V’ flavor.
- G6 leading to G#07 then Am7 utilizes a diminished chord (G#07) as a chromatic dominant substitute (E7b9), intensifying the resolution to the tonic minor.
- The Dm7-G7-Bm7b5-E7b9 sequence showcases back-to-back ii-V progressions, clearly outlining dominant functions for C major and A minor respectively.
- A descending chromatic bass line (Am, Am/G#, Am/G, D7/F#) provides sophisticated voice leading and momentum, common in minor key compositions.
Improvisation Focus A Harmonic Minor scale.
Difficulty Rating 3 (Intermediate) - The frequent ii-V changes, chromatic bass lines, and altered dominants require a solid understanding of minor key harmony and voice leading.
