Duet for Bow Chime & Live EEG

Duet for Bow Chime & Live EEG was a live improvisational performance recorded in the IMRC’s AP/PE on March 27, 2018.

This work uses a modified technique, which includes live EEG (brainwave) data in combination with bowing. EEG data processed through custom MaxMSP programming is converted to a sound signal and output through a pair of transducers attached to the resonator of the bow chime. 

The effect is such that the bow chime’s range of frequencies becomes focused where it is resonant with the EEG signal, and the two work together to produce complex layers of sound. Further, the normal haptic feedback loop between the bow chime and player, which allows the player to choose sympathetic bowing actions, is layered with the added element of biofeedback from the EEG sounds generated by the player in action.

An upcoming performance using this technique is scheduled for July 9, 2018, at the Apohadion Theatre in Portland Maine.

 

Champlin uses a modified bow chime developed by Matt Samolis. She has been studying ‘cymbal bath’ techniques with Samolis since 2017. The instrument is modeled on the original bow chime invented by Robert Rutman in 1967.
