Harmonic Highlights

  • Employs foundational ii-V-I sequences in C major, establishing a clear diatonic framework before introducing chromatic substitutions.
  • Features a distinctive C7 to F#7 transition, utilizing a tritone-related dominant bridge to lead into the IV chord (Fmaj7).
  • Incorporates subdominant minor functional harmony via the Fm6 chord, providing a classic “minor iv” resolution to the mediant Em7.
  • Utilizes secondary dominants with altered tensions (A7b9) to create a stronger pull through the extended turnaround sequences.

Improvisation Focus Guide tone navigation (targeting 3rds and 7ths) to maintain melodic continuity through the rapid harmonic rhythm.

Difficulty Rating 3/5; while the key center remains stable, the player must navigate sophisticated chromatic voice leading and minor-key substitutions effectively.
