Harmonic Highlights:
- Establishes a lyrical foundation through frequent diatonic I-vi-ii-V progressions in C major.
- Features secondary dominant chords with altered extensions, such as A7#9 (V7/ii), adding harmonic tension.
- Prominently tonicizes related minor keys using robust minor ii-V-i sequences, including Bm7b5-E7b9-Am7.
- The F#m7b5-B7b9 sequence further introduces transient modulations to the mediant minor.
Improvisation Focus: Altered Dominant Scales.
Difficulty Rating: 4/5. The frequent modulations to related minor keys, coupled with altered dominant chords, require a strong grasp of functional harmony and altered scales.
