Harmonic Highlights
- The opening Dm7-G7 establishes a prolonged ii-V progression leading to C, creating harmonic tension and delaying a clear G minor tonic.
- The G minor tonic (Gm7) is immediately followed by C7, functioning as a secondary dominant (V/F) and briefly tonicizing the bVII chord.
- Frequent use of secondary dominants (G7, C7) generates constant harmonic movement and implies shifting temporary tonal centers.
Improvisation Focus Mastering dominant chord alterations and resolutions to navigate the transient V7 chords.
Difficulty Rating 3 (Intermediate): Requires understanding of secondary dominants and adapting improvisation to frequent temporary tonicizations.
