Harmonic Highlights

  • Features prominent minor ii-V-i sequences (Em7b5 โ€“ A7b9 โ€“ Dm7) that tonicize the subdominant (iv) region.
  • Navigates between the relative major and minor through ii-V-I cadences in C Major (Dm7 โ€“ G7 โ€“ Cmaj7) followed by returns to A Minor.
  • Employs secondary dominants like D7 (V/V) to create chromatic tension before resolving to the G7 or returning to the tonic minor.
  • Frequent tonic-dominant oscillation (Am7 โ€“ E7) provides a stable harmonic foundation against more complex bridge modulations.

Improvisation Focus A Harmonic Minor to effectively bridge the gap between Am7 and the leading tone (G#) of the E7 dominant chords.

Difficulty Rating 3/5; the progression relies on standard functional harmony but requires smooth transitions between relative major and minor tonal centers.
