Harmonic Highlights
- Frequent, abrupt shifts between parallel major (Fmaj7) and minor (Fm7) tonalities.
- Extensive use of non-diatonic ii-V progressions leading to distant key centers (e.g., F#m7-B7 to E, Abm7-Db7 to Gb).
- Complex, rapid chains of ii-V movements (e.g., Abm7-Db7 then Dbm7-Gb7) generating challenging harmonic instability.
Improvisation Focus Chord-scale improvisation, emphasizing accurate articulation of temporary tonalities and distant key centers.
Difficulty Rating 5 (Advanced). The rapid, unpredictable modulations and complex non-diatonic ii-V cycles demand exceptional harmonic understanding and technical fluency.
