Harmonic Highlights

  • The opening Bbm/Eb (functioning as Eb11) -> Ebm7 -> Eb7 sequence establishes a distinctive minor blues or modal quality by using a minor tonic followed by its parallel major dominant.
  • A sophisticated Abm7 -> Ab7#11 -> G7 progression showcases the Ab7#11 (bVI7 with #11) functioning as a tritone substitution for D7 (V/G), leading powerfully to the C minor V7.
  • The C07 chord is employed as a chromatic passing or secondary diminished sonority, adding tension before the decisive bII7 -> V7 resolution to the C minor tonic.

Improvisation Focus Navigating the shifting dominant qualities, particularly using the altered scale (superlocrian) on the Eb7, Ab7#11, and G7 chords.

Difficulty Rating 4 (Advanced Intermediate) - The piece requires precise navigation of minor key harmony, sophisticated dominant alterations, and tritone substitutions within a shifting tonal landscape.
