- Frequent minor ii-V-i turnarounds (Bm7b5–E7alt–Am7) emphasize the relative minor, creating a sophisticated tension-release cycle against the C major tonic.
- Chromatic voice leading via the Ab°7 passing chord facilitates a smooth transition between the vi (Am7) and the ii of the subdominant (Gm7).
- Secondary dominants (C7, D7) and altered extensions (C7alt) create rapid directional shifts toward Fmaj7 and Gm9.
- The Bb9 acts as a “backdoor” dominant resolution, providing a non-diatonic bVII7 to I cadence common in post-bop jazz.
Improvisation Focus Voice leading through the Altered Scale (Super Locrian) on dominant chords to navigate the frequent minor-key resolutions.
Difficulty Rating 3/5; while the key center is C, the density of minor ii-V-I patterns and altered extensions requires intermediate knowledge of functional harmony and fluid scale switching.
