Diptych, for solo guitar (2015) – 10'

I. Overture
II. Passacaglia
Diptych was written for Isaac Greene, to whom it is dedicated. The Overture begins with trios of chords, which break into dotted rhythms, then reform. The Passacaglia’s line is extracted from those chords, initially spread widely, but converging closer (and sometimes inverting, or even simultaneously running inverted and normal) until, at the climax, it forms again into the chords that began the Overture.
