Harmonic Highlights:
- Features extended passages (8 bars each) of dominant suspended chords (Bb7sus, G7sus), establishing prolonged, static harmonic fields.
- Presents an abrupt modulation via a ii-V-I progression (Bm7-E7-Amaj7) into A major, following the static G7sus section.
- Introduces an immediate, chromatically distant shift from the Amaj7 tonic to Bbm7, creating a surprising harmonic juxtaposition.
- The pervasive use of ‘sus’ chords throughout the initial sections delays conventional resolution, creating a distinct modal tension.
Improvisation Focus: Modal improvisation over sustained suspended dominants.
Difficulty Rating: 4 (Advanced). Requires sustained creative development over prolonged static harmonies and navigating abrupt, chromatically distant modulations.
