Harmonic Highlights:
- The piece frequently shifts between D minor and its relative major, F major, establishing a flexible tonal center and modal ambiguity.
- Prominent use of secondary dominants like D7b13 (V7/iv) and G7#11 (V7/C with Lydian dominant quality) extends harmonic movement and tension.
- Chromatic altered dominants such as E7b9, A7#9, and the presence of Bb7#11 introduce complex color tones and imply tritone substitution possibilities.
Improvisation Focus: Altered Scale (Super Locrian) over the various dominant seven chords.
Difficulty Rating: 4 (Advanced Intermediate). The frequent altered dominants, secondary dominant chains, and shifting tonal centers demand a solid command of complex harmonic concepts.
