Harmonic Highlights

  • Employs frequent I7-V7 (Bb7-F7) alternations, drawing heavily from gospel “shout” traditions and blues-based call-and-response patterns.
  • Features an extended turnaround sequence (Am7-D7-Gm7-C7) which functions as a vii-III-vi-II progression, utilizing secondary dominants to drive momentum back toward the dominant.
  • The harmonic language relies almost exclusively on dominant 7th sonorities, creating a blues-inflected landscape that blurs the distinction between tonic and dominant functions.

Improvisation Focus The Bb Blues scale, specifically emphasizing the “blue” notes (Db, E, Ab) to maintain the soulful, vocalized character of the composition.

Difficulty Rating 3/5: While the harmonic changes are manageable, the fast 6/8 gospel meter and required rhythmic “swing” feel demand high-level coordination and phrasing.
