  • Harmonic Highlights:

    • F#07 functions as a chromatic passing diminished chord, providing smooth voice leading into the Gm7 (vii°7/ii to ii).
    • The Cm7-F7-Bbmaj7 sequence executes a temporary tonicization of the IV chord (Bb major), a common element in standards.
    • The Am7-D7-Gm7-C7 progression is a classic iii-VI-ii-V turnaround, strongly reinforcing the F major tonality.
    • The Dm7-G7-C7 sequence acts as a ii-V of C, which is the V chord of the home key F.
  • Improvisation Focus: Navigating ii-V-I and iii-VI-ii-V progressions using F Major modes and arpeggios.

  • Difficulty Rating: 3 (Intermediate). It features standard jazz progressions and common substitutions, requiring a foundational understanding of functional harmony and modal interchange.
