Harmonic Highlights

  • Employs a modified 12-bar blues structure adapted for 3/4 time, integrating ragtime-influenced syncopation into a jazz framework.
  • Utilizes chromatic diminished passing chords (Gยฐ7 and C#ยฐ7) to create tension and smooth voice-leading transitions between the G7 tonic and D7 dominant.
  • Features a secondary dominant turnaround (E7โ€“A7b9โ€“D7b9) that provides a strong cyclical resolution back to the G major tonic.

Improvisation Focus The G Blues scale (G, Bb, C, Db, D, F) combined with G Mixolydian.

Difficulty Rating 3/5; while the harmonic changes are primarily blues-based, the “raggy” 3/4 syncopation and chromatic diminished substitutions require intermediate rhythmic precision and voice-leading skills.
