Harmonic Highlights
Features extensive use of minor tonic chord alterations (Dm/maj7, Dm7, Dm6; Gm/maj7, Gm7), creating smooth chromatic voice leading over sustained harmony.
Includes a prominent minor ii-V-i progression (Em7b5-A7-Dm), strongly tonicizing D minor as a temporary center within the overall G minor key.
Utilizes secondary dominants like D7 to propel motion towards the G minor key center, enhancing harmonic direction.
Incorporates a distinct modulation to Db major via a clear ii-V-I progression (Bbm7-Ebm7-Ab7-Db6), providing significant harmonic contrast.
Improvisation Focus Chord-scale relationships, adapting to minor tonality and temporary modulations.
Difficulty Rating 4 (Advanced) - The blend of minor tonic alterations, ii-V-i progressions, and significant modulations requires a sophisticated harmonic approach.
