Harmonic Highlights
- Utilizes the IV7#11 (Gb7#11) to establish a Lydian Dominant texture, providing a sophisticated departure from standard diatonic functional harmony.
- Employs secondary dominant chains (F7b9 → Bb7 → Ebm7) to create a strong directional pull through the circle of fifths toward the supertonic.
- Frequent ii-V-I turnarounds (Ebm7 - Ab7 - Dbmaj7) reinforce the C#/Db major center while facilitating smooth transitions between dense harmonic shifts.
- Chromatic movement between the iii (Fm7) and ii (Ebm7) via the VI7 (Bb7) chord showcases elegant voice-leading typical of the Great American Songbook.
Improvisation Focus Guide Tone Navigation to effectively connect the shifting 3rds and 7ths across the frequent secondary dominant changes.
Difficulty Rating 3/5: While the slow ballad tempo is accessible, the constant stream of secondary dominants and wide melodic leaps requires disciplined harmonic mapping and precise ear training.
