supergravity started with the physical fact that frequency rises as wavelength decreases. In other words, sound becomes higher pitched as it gets faster. This notion is related to the rhythm/pitch duality that exists inherently with sound — rhythm, as it speeds up, becomes so fast that it becomes perceived as a pitch. I decided I would use 11 sequentially pitched percussion instruments using drums, wooden planks, and woodblocks, with each new section faster than the previous and using a higher-pitched percussive instrument. When I think of dualities and the number 11, my mind jumps to string theory, (specifically M-theory), which contains the notion of 11 dimensions. Part of string theory includes the idea of supergravity, and hence the title of the piece. But, making another jump in inspiration, I composed the piece in a way that reminds me of the abstract expressionist “action paintings” of Jackson Pollock, in which paint splashes and drips onto the canvas in accordance with gravity. When I composed this piece, I moved freely between the 11 sections, (or dimensions if you like), splashing little bits of music into them.
