Harmonic Highlights
- The prevalent
Fm7-Bb7(IIm7-V7) progression firmly establishes Eb major, providing clear cadences. - Secondary dominants like
C7(V7/II) andC7b9(V7b9/II) introduce effective temporary tonicizations of Fm7. - The unique
Fm - Fm/maj7 - Fm7movement creates a subtle chromatic tension, hinting at a minor tonic with a major 7th resolution.
Improvisation Focus Targeting chord tones and dominant alterations, especially over secondary dominants.
Difficulty Rating
3 - Intermediate. The core progressions are accessible, but secondary dominants and the unique Fm/maj7 chord require harmonic awareness beyond basic diatonic playing.
