Delta 5 (1:00, 2014)
This is a symmetrical design of musical events characterized by time (when the event occurs), pitch, intensity, timbre, and pan position. Each such event here is part of an ten-member family determined by permuting and inverting the five parameters – that’s the sense in which the design is symmetrical. “Δ5” is one name for the abstract group of this symmetry. The sounds here are generated by modal synthesis using Reaktor Prism (Native Instruments) under control of Digital Performer (Mark of the Unicorn). The pitch scale is 61.5 cents per step.
