| Eb7 | 12 | 50.0% |
No obvious ii-V patterns detected.
Harmonic Highlights:
- Dominant 7th quality applied to both the V (F7) and IV (Eb7) chords within the Bb minor key center.
- Establishes a static two-chord vamp (V7-IV7) that continuously suspends tonic resolution to Bb minor.
- The perpetual oscillation between F7 and Eb7 creates a modal, blues-inflected harmonic environment, characteristic of a sustained groove.
Improvisation Focus: Bb minor blues scale.
Difficulty Rating: 3 (Intermediate) The simple two-chord vamp is harmonically straightforward, but maintaining melodic interest and navigating the dominant 7th qualities effectively requires an intermediate improvisational approach.
