Harmonic Highlights:
- Nuanced exploration of the D minor tonic using
Dm, Dmb6, Dm6, Dm7, implying various minor scale qualities (natural, Dorian, melodic). - Extensive application of altered and substituted dominant chords, notably
B7#5#9,Bb7#11, andA7#5#9, creating sophisticated chromatic tension. - Strategic use of secondary dominants, like
D7b9(V7 of Gm), and subtle modal interchange elements from F major (relative major).
Improvisation Focus: Altered scales derived from the minor melodic mode.
Difficulty Rating: 5 (Advanced). The dense use of altered dominants and complex substitutions requires deep harmonic knowledge and precise scale application.
