Harmonic Highlights

  • The progression utilizes a sophisticated opening IVmaj7 to VII7#9 to iii7 (Fmaj7#11โ€“B7#9โ€“Em7), where the B7 functions as a secondary dominant (V/iii) to the mediant.
  • Frequent minor ii-V-i cells (Bm7b5โ€“E7b13โ€“Am7) pull the tonality toward the relative minor, requiring a shift to A harmonic minor.
  • The use of secondary ii-V patterns (Gm7โ€“C7) tonicizes the subdominant (Fmaj7), adding harmonic depth beyond simple C major diatonicism.
  • Inversions and descending bass lines (Am7/E to Dm7/C) create smooth scalar voice leading through the bridge and transitions.

Improvisation Focus Navigating the frequent shifts between C major and A melodic/harmonic minor over the minor ii-V-i progressions.

Difficulty Rating 3 (Intermediate). The song is mostly diatonic but requires fluid navigation of secondary dominants and minor-key turnarounds that temporarily deviate from the home key.
