This is a piece for piano and harp. It is a kind of dialogue between two instruments that have many things in common, especially their inherent shape. Both instruments are constructed with a beautifully triangulated geometry, and the drawings play with the idea of variations in the disposition of triangles. It is the idea of discourse - of a conversation between two instruments, both played with the fingers but one making sound by being plucked and the other by means of hammers activated by two hands - that caused these studies to be abstract and not representational like many studies for other pieces of mine.
