Harmonic Highlights

  • Contrafact Structure: Built on the changes of “Embraceable You,” the progression oscillates between Eb Major and its relative minor, C minor, utilizing secondary dominants like G7 to reinforce the minor center.
  • Cyclic Dominants: The bridge employs an extended cycle of fourths (Am7-D7-Gm7-C7-F7-Bb7), requiring the soloist to navigate rapid tonal shifts through various temporary key centers.
  • Linear Bass Motion: The sequence Cm7 - Cm7/Bb - Am7 creates a chromatic-descending line in the bass, providing a smooth harmonic bridge between the tonic Ebmaj7 and the upcoming dominant cycles.

Improvisation Focus Bebop scales and chromatic enclosure patterns targeting 3rds and 7ths within ii-V-I cells.

Difficulty Rating 4 (Advanced): The dense harmonic rhythm and rapid movement through secondary dominants require high-level fluency in bebop vocabulary and sophisticated voice-leading skills.
