Harmonic Highlights

  • The progression centers on a minimalist i-V7 (Am to E7) turnaround, maintaining a high level of tonal stability and a static harmonic environment.
  • Tension is generated primarily through rhythmic displacement and “stop-time” figures rather than functional harmonic density or complex extensions.
  • Standard arrangements utilize periodic half-step modulations (e.g., Am to Bbm), transposing the entire structure upward to increase intensity across the song’s form.

Improvisation Focus A Minor Blues Scale.

Difficulty Rating 1/5. The slow harmonic rhythm and repetitive two-chord structure allow performers to focus entirely on rhythmic pocket and basic melodic development.
