Harmonic Highlights:
- Extensive use of modal interchange, notably
Fm7(iv minor) andEbmaj7(bVIImaj7), enriching the F major tonality with borrowed minor modes. - Strategic secondary dominants and ii-V progressions leading to temporary tonicizations, such as
Em7b5 - A7 - Dm7(ii-V-i of D minor). - Abrupt chromatic shifts and tritone substitutions, exemplified by
B13andGbmaj7#11(a bIImaj7#11), creating advanced harmonic ambiguity and tension.
Improvisation Focus: Accurate chord-scale application for navigating rapid modal and chromatic shifts.
Difficulty Rating: 5 (Advanced) – Requires sophisticated understanding of modal interchange, chromatic substitutions, and complex non-functional harmony.
