B7#9 -> EmResolution (Minor)1

Harmonic Highlights:

  • The progression centers on a tonic-prolongation minor vamp, oscillating between the i (Em) and bVI7#11 (C7), creating a Lydian Dominant color that avoids traditional functional resolution.
  • The inclusion of the bII7 (F7#11) serves as a chromatic neighbor chord, providing a Neapolitan-style shift that reinforces the “mystery” aesthetic of the theme.
  • The turnaround utilizes a bVI7 to V7#9 movement (C7 to B7), emphasizing a high-tension dominant resolution that draws from both blues and hard bop traditions.

Improvisation Focus: The E Minor Blues Scale, specifically utilizing the #4/b5 as a chromatic passing tone to mirror the signature “creeping” melody.

Difficulty Rating: 2/5. The harmonic rhythm is slow and repetitive, making it accessible, though players must navigate the #11 extensions on the non-functional dominant chords.
