🎼 Sheet Music
Find Lead Sheet on Sheet Music Direct (PDF)Harmonic Highlights:
- The progression opens with a I-VI-ii-V in the relative major (Eb), utilizing C7b13 as a secondary dominant (V/ii) to create chromatic tension.
- It frequently pivots between Eb Major and C Minor, using the Dm7b5 - G7b9 cell to reinforce the minor tonality.
- The structure relies on functional diatonic movements interspersed with altered dominant extensions, particularly the b13 and b9, to facilitate smooth voice leading.
- The harmonic rhythm is consistent, alternating between stable tonic centers and active ii-V turnarounds.
Improvisation Focus: Navigating the Major-to-Relative-Minor pivot, specifically applying C Harmonic Minor over the G7b9 to Cm7 resolutions to highlight the leading tone (B natural).
Difficulty Rating: 3/5: While the changes are functional, the frequent shifts between major and minor ii-V-I patterns require precise scalar navigation and awareness of chromatic alterations.
