- Utilizes a recurring ii-V-I in Ab major that begins on the ii chord (Bbm7), creating a typical bebop delayed resolution to the tonic Abmaj7.
- Features minor ii-V turnarounds (Cm7b5–F7) to target the ii chord (Bbm7), introducing sophisticated harmonic tension within a major key context.
- The bridge employs a ii-V to the IV chord (Dbmaj7), followed by a Gb7#11 (bVII7), functioning as a “backdoor” dominant resolution back to the tonic.
- Incorporates II7 (Bb7#11) secondary dominants, providing a Lydian Dominant color that bridges the gap between the tonic and the primary dominant.
Improvisation Focus Navigating the Ab major bebop scale while utilizing the Lydian Dominant mode over the Gb7#11 and Bb7#11 extensions.
Difficulty Rating 3/5. The structure is logical, but the frequent secondary dominants and chromatic ii-V sequences require melodic fluency at fast bebop tempos.
