"Divination by Mirrors" is a roughly ten-minute work featuring the bowed saw, accompanied by a string orchestra that is divided into two groups of players tuned 1/4 step apart and occupying opposite sides of the stage. The piece has eight Sections, each named for a different kind of divination --foretelling the future by means of the occult. The unifying compositional idea is an exploration of the myriad possibilities of musical symmetry. These include pitch and time mirrors of various sorts, counter-balancing journeys into the two different pitch "universes" of the oppositely-tuned halves of the orchestra, and extensive use of the architectural concept of "dynamic symmetry" in defining durations of Sections, sub-sections, and tempi.
