Harmonic Highlights:
- Features prominent use of D7 (II7) as a secondary dominant (V7/G), creating a strong dominant sound early in the progression.
- Includes a “backdoor” dominant progression (Fmaj7 - Bb7 - C6), where Bb7 (bVII7) resolves to the tonic.
- Utilizes a chromatic descending diminished chord: Em7 - Eb07 - Dm7, providing sophisticated voice leading to the ii chord.
- Incorporates Fm6 (minor iv chord) borrowed from the parallel minor, adding a distinctive melancholic color.
Improvisation Focus: Navigating secondary dominants and chromatic passing tones.
Difficulty Rating: 3 (Intermediate). It combines fundamental II-V-I movements with jazz-specific elements like secondary dominants, backdoor dominants, borrowed chords, and chromatic diminished passing chords.
