Harmonic Highlights

  • Prominent use of the III-VI-II-V (Am7-D7-Gm7-C7) progression reinforcing the F major tonic.
  • Characteristic I7/III (F7/A) chord often preceding the subdominant Bb6.
  • Strategic deployment of the chromatic diminished B07 as a passing chord between Bb6 and F6/C.
  • Frequent tonicization of the IV chord (Bb) through its ii-V progression (Cm7-F7).

Improvisation Focus F Major scale and its diatonic modes (Dorian for minor, Mixolydian for dominant 7ths) for navigating II-V-I progressions.

Difficulty Rating 3/5 - Features clear diatonic harmony with standard jazz substitutions and common chromatic passing chords, requiring moderate harmonic awareness.
