Gallery 400, Chicago Between Sound and Vision || Vertical 'lyre I (review) February 2001 | (hear installation) | The Vertical 'lyre is a multimedia instrument using pine beaters set in motion by subaudio pulses received from speaker-pumps located beneath the instrument. The pine beaters, or pendulums, are balanced to effect specific rhythmic patterns when striking adjacent pitch lines (nylon line) which are tuned and amplified by threaded piezo microphones. The instrument is controlled using an audio CD containing sub-audio pulse patterns along with audible sounds (does not affect pendulum movement) heard within a stereo field, or proscenium and delimited by the left and right speaker-pumps. The instrument is also designed for two 13-inch video monitors positioned within the opening in the back. The hammered strings can either be amplified by the television speakers or external speakers.
