Harmonic Highlights

  • Chromatic ascending basslines utilizing passing diminished chords (Gmaj7 - G#°7 - Am7 - Bb°7) to bridge diatonic steps smoothly.
  • Integration of the “line clichĂ©” (Am - Am/maj7 - Am7) creating internal chromatic voice leading within tonic minor structures.
  • Rapid modal shifts between the A minor home key and E major, often facilitated by II-V cycles (F#m7 - B9 - Emaj7).
  • Employment of tritone substitutions (Bb9#11) functioning as sophisticated dominant preparations leading back to the Am tonic.

Improvisation Focus Melodic Minor Scale

Difficulty Rating 3/5: The tune’s reliance on chromatic passing tones and shifting tonal centers requires precise navigation of voice leading and non-diatonic extensions.
