Harmonic Highlights

  • The progression utilizes minor ii-V-i cells (Am7b5โ€“D7b9) that frequently resolve deceptively to the relative major (Gmaj7), blurring the line between E minor and G major.
  • A prominent chromatic turnaround (Bm7โ€“Bb7โ€“Am7โ€“Ab7#11) uses tritone substitutions to create smooth melodic gravity toward the tonic.
  • The bridge incorporates secondary dominants and modal interchange (C7 and A7), requiring quick shifts in tonal centers while maintaining a cohesive ballad structure.

Improvisation Focus Mastering the transition between E Harmonic Minor (for V7-i resolutions) and G Major/Ionian, while applying Lydian Dominant over the Ab7#11 tritone substitution.

Difficulty Rating 3/5 - The slow tempo allows for careful note choice, but the frequent chromatic ii-V sequences and non-diatonic dominant chords require sophisticated harmonic awareness.
