Harmonic Highlights:
- Extensive prolongation of the tonic
Abm7firmly establishes the G# minor key initially. - Features clear ii-V-I progressions to distant tonalities, such as
Bbm7-Eb7#9-Dbmaj7(Db major is bIII of G# minor). - Incorporates a distinct
Gm7b5-C7-Fmaj7ii-V-I leading to F major, a non-diatonic key (bVI of G# minor). - Employs a sequence like
F#m7-B7-Emaj7-A7, indicating passing modulations or chromatic dominant movement rather than a single stable tonality.
Improvisation Focus: Navigating rapid modulations by accurately outlining chord tones and applying appropriate modes.
Difficulty Rating: 4 (Advanced Intermediate). The piece demands quick adaptation to frequent, non-diatonic key changes and advanced chord voicings.
