Harmonic Highlights:
- Frequent secondary dominant function, notably A7 (V/D) leading to D7 (V/Gm), establishing strong dominant motion towards G minor.
- Blues-inflected dominant alterations are prevalent, such as Eb7 (bVI7) acting as a tritone substitution for A7, and the highly altered Db7#5 (V7alt/C) preceding C7-F.
- Modulatory excursions shift from G minor towards its relative major (Bb) with Bb7, and transiently to F major via a strong G7-C7-F cadence.
- Chromatic passing diminished chords like B07 create tension and lead effectively to subsequent dominant chords.
