The Variable Theremin Collaborative is a multidisciplinary performance that coordinates performance between participants by means of audible and visual feedback derived from each performer. The feedback takes the form of collaborative instruments, which require the performance of two dancers to function. There are two primary feedback vehicles: a theremin and video processor. The musicians -- Joe Adamik (percussion), Marina Peterson (cello) and Jesse Peterson (violin) -- will improvise, providing multiple potential inputs for the theremin.

A demonstration of this performance is scheduled from 2 to 5 p.m. Wednesday, March 12, at the Aesthetic Technologies Lab in Putnam Hall 235. The Variable Theremin Collaborative will perform at 9 p.m. the same day in Seigfred Hall's Mitchell Auditorium. The group will also host a workshop from 10 a.m. to noon Thursday, March 13, at the Aesthetic Technologies Lab.

The theremin is a musical instrument that relies on two inputs to produce a single synthesized tone. The first input controls the frequency of the audible output, the second input controls volume. The result of the combination of the inputs is a monophonic, highly variable linearly controlled musical instrument. In a traditional theremin both inputs are controlled by a single player.

The Variable Theremin Collaborative expands on the traditional theremin by allowing elements of two dancers' performances to be mapped to inputs on a virtual theremin. The quintessential example of this is mapping a dancer's position relative to the front or back of the stage to the volume of theremin."
