Harmonic Highlights
- Prominent use of diatonic ii-V-I progressions in Eb major, establishing the tonic.
- Frequent tonicization of the relative minor (C minor) via Dm7b5-G7b13-Cm7, introducing a minor-key flavor with an altered dominant.
- Incorporation of secondary dominants (e.g., C7 as V/F) to extend harmonic movement beyond simple diatonicism.
- Application of chromaticism, including the Abm6 and Gb07 chords, adding color and tension before resolutions.
Improvisation Focus Mastery of ii-V-I resolutions across major, minor, and altered dominant contexts.
Difficulty Rating 4 (Advanced Intermediate) - The blend of standard progressions with altered dominants (G7b13), chromatic chords (Abm6, Gb07), and functional shifts demands a sophisticated understanding of jazz harmony.
