- Utilizes tritone substitutions such as B7 (subV7/IV) and Eb7 to create chromatic, non-diatonic transitions into the IV and I chords.
- Employs modal interchange between F major and F minor (e.g., Fm7 to Bbm7), adding a “blues-noir” harmonic texture characteristic of Hefti’s style.
- Features secondary dominant chains and II-V-I cycles (Am7–D7 to Gm7–C7) that provide melodic momentum while reinforcing the F major tonality.
Improvisation Focus The F Blues scale integrated with chord-tone targeting to navigate the frequent chromatic substitutions and shifting II-V-I cells.
Difficulty Rating 3/5: While the relaxed tempo is approachable, the constant chromatic modulations and non-diatonic dominant chords require advanced harmonic awareness and precise note selection.
