Harmonic Highlights:
- The opening Eb9-Ebm7-Dbmaj7 progression creates a distinctive bII-ii-I movement in Db major, functioning as a sophisticated tonicization of the bIII chord in Bb minor.
- Bb7b5b9 serves as an altered V7/IV, building significant tension before resolving to the subsequent Eb9 (bII/bIII).
- A clear modulation to Eb major (IV) is established by the ii-I progression of Fm9-Ebmaj7, offering a brighter contrast to the minor key center.
- The harmony frequently employs modal interchange, blending elements of Bb minor with temporary tonicizations of Db major and Eb major.
Improvisation Focus: Modes of the melodic minor scale provide the most adaptable melodic framework for navigating the frequent modal shifts and altered dominant chords.
Difficulty Rating: 4 (Advanced Intermediate). The frequent, sometimes rapid, changes to non-diatonic major and altered dominant chords require a strong grasp of functional harmony and modal improvisation.
