Harmonic Highlights:
- Extensive use of the A7sus chord, creating a prolonged sense of harmonic suspension before its resolution to the D major tonic.
- Frequent integration of modal interchange chords, notably Gm7 (iv from D minor) and the iiø7-V7b9 progression (Em7b5-A7b9), which temporarily evokes a D minor tonality.
- The Am/D chord functions as a Dm7, providing a distinctive minor tonic color that subtly contrasts with the prevailing D major tonality.
- The unexpected appearance of Amaj7 introduces a non-diatonic element, suggesting either a brief tonicization of A major or a sophisticated harmonic reinterpretation.
Improvisation Focus: Navigating D major and D minor modal interchange.
Difficulty Rating: 3 (Intermediate) - Requires understanding of modal interchange and the ability to articulate harmonic shifts beyond simple diatonic harmony.
