Harmonic Highlights
- Clear V-I resolutions in F major, often preceded by secondary dominants like Am7-D7 (iii-VI or ii-V/ii).
- Frequent use of altered dominants, such as C7#5, enhancing V7-I tension.
- Chromatic embellishments and substitutions are present, exemplified by G#07 and Gb7b5 (tritone sub for C7).
Improvisation Focus Navigating altered dominant 7th chords with appropriate scales (e.g., Altered scale, Lydian Dominant).
Difficulty Rating 3/5. It features standard ii-V-I progressions but introduces sophisticated altered dominants and substitutions that require specific harmonic awareness.
