No obvious ii-V patterns detected.


Harmonic Highlights:

  • Prominent use of the bVI (Eb) chord, often preceding the V7 (D7), establishing a characteristic minor key color.
  • The D7 functions as a strong V7 of G minor, utilizing the leading tone for dominant resolution.
  • Introduction of C7 as a secondary dominant (V7/F, i.e., V7/bVII), injecting a blues-inflected or modal interchange element.
  • Repetitive phrasing in the sample (Eb, Eb, D7, D7) creates a foundational rhythmic and harmonic vamp, typical of early jazz.

Improvisation Focus: Harmonic minor over the V7 (D7) and Mixolydian over the secondary dominant (C7).

Difficulty Rating: 3 (Intermediate). Requires awareness of minor key dominant functions and secondary dominant resolution.
