🎼 Sheet Music
Find Lead Sheet on Sheet Music Direct (PDF)Harmonic Highlights:
- Tritone Polarity: The composition pivots between G major and Db major, demanding navigation of two tonalities separated by a tritone.
- Lydian Dominant Usage: The integration of IV7#11 (C7#11) and bII7#11 (Gb7#11) emphasizes bright, non-resolving dominant colors over functional V-I cadences.
- Chromatic Parallelism: The progression utilizes “side-slipping” logic, moving ii-V cells (like Ebm7-Ab7) into distant keys without traditional diatonic preparation.
Improvisation Focus: Mastery of the Lydian Dominant scale (4th mode of Melodic Minor) and navigating the abrupt modulation between G and Db tonal centers.
Difficulty Rating: 4/5. The rapid shifts between distant keys and the reliance on non-functional dominant harmony require advanced modal proficiency and quick mental transposition.
