Harmonic Highlights
- Prominent use of diatonic ii-V-I progressions in F major.
- Clear tonicization of the relative minor (Dm) via Em7b5-A7-Dm7.
- Effective use of secondary dominants, such as F7/A (V/IV) leading to Bb.
- A striking, brief modulation to the distant key of A major via Bm7b5-E7-Amaj7.
Improvisation Focus Navigating sudden modulations using arpeggio superimposition.
Difficulty Rating 4 (Advanced Intermediate). While common ii-V-I patterns are present, the unexpected, distant modulation to A major requires precise harmonic awareness.
