Harmonic Highlights
- Frequent ii-V-I progressions (Gm7-C7-F6) establish and reinforce the primary key of F major.
- Utilization of chromatic diminished chords, such as F#07 (often functioning as viiø7/ii or a passing diminished), adds color and leads to new sections.
- A clear, strong modulation to Ab major is presented through a ii-V-I progression (Bbm7-Eb7-Abmaj7), introducing a temporary new tonal center.
Improvisation Focus Navigating temporary tonicizations and modulations with corresponding scale and arpeggio applications.
Difficulty Rating 3 (Intermediate) because while core ii-V-I patterns are straightforward, the distinct modulation to Ab major and the frequent use of chromatic diminished chords require attentive harmonic awareness.
