PLOrk and Opposite Earth

Jeff Snyder's Opposite Earth performed by PLOrk

"This is an animated notation piece for an open instrumentation. It was written for PLOrk in 2017 and can be performed by a combination of acoustic and electronic musicians. The graphic score is realized using the p5 javascript library. The conductor changes the image components live to guide the course of the piece. For instance, the conductor can add and remove rings (performers), planets (pitches), and ticks (percussive sounds) at will. The color of the lines conveys which of five possible pitch gamuts is used. Moons are played by the same performers that are handling the planet they orbit around." (text from YouTube description)
