- Prominent use of the ii-V-I progression (Bbm7-Eb7-Abmaj7) as a foundational harmonic cadence.
- Secondary dominants such as F7 (V7/Bb) and Bb7 (V7/Eb) frequently appear, creating momentum before the main ii-V.
- The progression Fm7-Bb7 (a ii-V to Eb) often resolves to Eb7, functioning as the V chord of Ab, illustrating a common ii-V of V structure.
Improvisation Focus: Ab Major scale and its diatonic modes (Dorian for ii, Mixolydian for V) are essential for navigating the ii-V-I changes.
Difficulty Rating: 2 (Beginner-Intermediate). The harmonic vocabulary is standard jazz, relying heavily on fundamental ii-V-I progressions and common secondary dominants, making it accessible for foundational study.
