Harmonic Highlights
- Frequent use of the bVII7 chord (Eb7), functioning both as a backdoor dominant to Fmaj7 and as a tritone substitute leading to Dm7.
- Classic iii-V/ii-ii-V-I progression (Dm7-G7-Gm7-C7b9-Fmaj7) showcases strong functional harmony.
- Clear temporary tonicization of the subdominant (Bb major) via ii-V-I progressions (Cm7-F7-Bbmaj7).
- A colorful iiø-V (Em7b5-A7b13) leading deceptively from the relative minor (D minor) to the subdominant (Bbmaj7).
Improvisation Focus Targeting Chord Tones.
Difficulty Rating 3 (Intermediate). Features standard ii-V-I progressions alongside modulations, tritone substitutions, and a deceptive cadence requiring attention to altered dominants.
