The idea for this work arose some time ago while I was studying Berio’s Sequenzas and the musical vocabulary of the works of Franco Donatoni. The word Duplum carries multiple connotations that transcend its primary meaning, i.e., adding one voice to another that already exists. Duplum is semantically connected to the Latin word duplicare (meaning “to duplicate”). Through this meaning it also conveys the idea of something in nature that grows, proliferates, and changes into something else but maintains structural relation with its origin. Duplum is conceived in sections which I refer to as panels. In each panel there is a reiteration of “figure” (figures), that are characterized by sound, rhythmic articulation and gesture and that are passed from one instrument to another, eventually evolving into other figure.
The way in which panels follow each other with relations of either similarity or opposition shapes the form of this work. This principle can be understood as analogous to modularity in painting, which some describe as integration of partially independent and interacting units.
