Harmonic Highlights:
- Prominent tonicization of the relative major (Bb Major) with
Bb6 - F7#5, introducing early harmonic contrast. - Frequent use of altered dominants, specifically
F7#5andC7#5, to create heightened tension and chromaticism. - The repeated
C7andC7#5chords function as either a secondary dominant (V7/F) or a blues-inflected IV7, adding forward motion. - A distinctive
Cm7 - Ebm6progression provides rich minor key coloration and a surprising modal shift.
Improvisation Focus: Applying altered scales (e.g., Lydian Dominant, Altered) over the prominent altered dominant chords.
Difficulty Rating: 3 (Intermediate). Requires understanding of secondary dominants, altered scales, and navigating temporary tonal centers within a minor key.
