Harmonic Highlights
- The opening section features a clear I-ii-iii-V7/ii-ii-V progression (Eb6, Fm7, Gm7, C7b9, Fm7, Bb7), showcasing functional harmony with a strong secondary dominant (C7b9 resolving to Fm7).
- A significant chromatic modulation occurs with Ebm7, C#m7, F#7, Bmaj7, which represents a ii-V-I in B major (bVImaj7 relative to Eb), preceded by Ebm7 (bVIIm7).
- The composition incorporates a iiø7-V7b13-i progression (Fm7b5, Bb7b13, Ebm7) to briefly tonicize the parallel minor key of Eb (Ebm).
Improvisation Focus Applying chord-scale theory to navigate rapid, non-diatonic key changes.
Difficulty Rating 4 (Advanced). The significant chromatic modulation to B major and subsequent shift to the parallel minor demand advanced harmonic understanding and improvisational agility.
