- The core progression Fm7 - Gm7 - Abmaj7 - Gm7 establishes a repetitive minor vamp rather than a strong functional harmonic progression.
- The inclusion of Gm7 as a minor 7th (not half-diminished) points strongly to an F Dorian modal context, where Gm7 functions as the ii chord.
- Abmaj7 acts as the bIIImaj7 chord, reinforcing the minor tonality while contributing to the vamp’s cyclical, non-resolving nature.
- This static, blues-infused vamp creates an open harmonic landscape, characteristic of groove-oriented modal jazz.
Improvisation Focus: F Blues Scale (F, Ab, Bb, B natural, C, Eb)
Difficulty Rating: 2 (Beginner-Intermediate). The consistent, repetitive modal vamp and lack of complex harmonic changes make it approachable for developing improvisers.
