Harmonic Highlights
- Predominant use of minor ii-V-i progressions (Bm7-E7-Am7) firmly establishing the A minor tonality.
- Frequent deployment of secondary dominants, such as D7 (V7 of G) and A7 (V7 of D), driving motion to non-tonic chords.
- Brief, yet effective, tonicization of the relative major (Dm7-G7 to C) and the IV chord (Em7-A7 to D).
- The C6 chord provides a momentary major color (III major) offering contrast before returning to minor functionality.
Improvisation Focus A melodic minor scale and its modes for navigating the complex dominant and minor chord qualities.
Difficulty Rating 4/5. Requires improvisers to navigate rapid key center shifts and apply appropriate modal or altered dominant concepts.
