Harmonic Highlights
- The prominent F69 (bIIImaj7) frequently acts as a blues-infused tonic substitute or borrowed chord, establishing an immediate non-diatonic or modal-interchange flavor.
- The progression frequently oscillates between D major (Dmaj9) and D minor (Dm9, A7b9#5 resolving to Dm9), showcasing sophisticated parallel mode interchange.
- The Db69 and Gb69 sequence introduces highly chromatic sidestepping or exotic substitutions, challenging diatonic expectations before returning to D-centric harmony.
- The use of G13 (IV7) instead of a diatonic Gmaj7 emphasizes a strong blues or dominant-centric influence even within D major sections.
Improvisation Focus Mastering the fluid navigation of parallel major/minor mode interchange (D major/minor) and incorporating blues scale inflections.
Difficulty Rating 4/5 (Advanced) – It demands adeptness in navigating frequent major/minor mode shifts, unexpected chromatic chords, and complex dominant voicings.
