Harmonic Highlights
- A classic I-V-I progression (Ebmaj7 - Bb7b9 - Ebmaj7) clearly establishes the Eb major tonality.
- The prominent Bb7b9 chord provides a characteristic Gypsy Jazz sound, blending major key resolution with minor-key dominant tension.
- The inclusion of Eb7 (and Eb7b9) functions as a secondary dominant (V7/IV) or a blues-inflected dominant, introducing chromaticism and leading tendencies.
Improvisation Focus The Phrygian Dominant scale (fifth mode of harmonic minor) is crucial for navigating the V7b9 chords and capturing the genre’s authentic sound.
Difficulty Rating 3 (Intermediate). The foundational changes are simple, but improvising authentically over the altered dominants requires specific scale and phrasing knowledge beyond basic diatonic concepts.
