Harmonic Highlights

  • The A section utilizes a descending chromatic line cliché (G - Gb - F - E) over the G minor tonic, providing internal melodic motion within a static harmonic block.
  • The progression employs a bVI7 (Eb7) as a chromatic approach or tritone substitute leading toward the dominant D7, reinforcing the minor-key tension.
  • The bridge shifts tonality via a ii-V-I progression to the subdominant (Eb major) and relative major (Bb major), utilizing standard jazz cycles to provide tonal contrast to the G minor head.

Improvisation Focus

The G Blues Scale (G, Bb, C, Db, D, F) is the essential concept for navigating the minor tonality while maintaining the “swing” feel characteristic of the Ellington era.

Difficulty Rating

2/5 (Beginner-Intermediate) because the repetitive AABA structure and predictable harmonic rhythm make it highly accessible for students learning to navigate minor-key chromaticism.
