Harmonic Highlights
- The opening IVmaj7 to #IV7b5 (Gbmaj7 - G9b5) creates a signature Strayhorn tension that resolves to a tonic chord voiced over its dominant (Dbmaj7/Ab).
- The use of a constant Ab pedal point under the initial tonic resolutions creates a floating, suspended atmosphere typical of Ellingtonian ballads.
- The B-section features a ii-V (Gm7b5 to C7b9) leading to the iii chord (Fm), providing a dark, minor-key contrast to the primary major-key lyricism.
Improvisation Focus
Lyrical phrasing using the Db Major scale, specifically emphasizing the Lydian #4 over the Gbmaj7 to navigate the chromaticism of the G9b5.
Difficulty Rating
4/5: The slow tempo requires immense control over tone and space, while the non-functional chromaticism demands precise guide-tone navigation.
