🎼 Sheet Music
Find Lead Sheet on Sheet Music Direct (PDF)Harmonic Highlights:
- The transition from Em7 to Em7b5 signifies a shift from D Major/Dorian colors to a darker D Minor/Phrygian landscape.
- Eb7 to Dmaj7 acts as a tritone substitute ($b$II7-I), providing a deceptive resolution from the minor-heavy introduction to a bright Major tonic.
- Non-functional “constant structure” movements (Abm7 to Gbmaj7) showcase Corea’s trademark use of parallel harmonic shifts and chromaticism.
- The Gm7/D pedal creates a IVm/I ambiguity, anchoring the harmony in D while exploring subdominant minor textures.
Improvisation Focus: Modal Interchange (navigating the rapid shifts between D Dorian, D Phrygian, and D Lydian/Major).
Difficulty Rating: 4/5. The non-functional transitions and complex modal layering require a high level of harmonic fluency beyond basic diatonic progressions.
