and a video
Starting with the simplest of sound material — sine waves — this piece slowly builds up into a noisy, yet tactile, interactive performance piece. Video projections onto the sheet become part of the user interface which can be controlled with physical gestures. Layers of sound differing in length are looped creating complex rhythms. Other techniques include feedback: contact microphones placed on harmonic ‘nodal’ points in the sheet are amplified back through the infra sound driver, creating rich harmonic oscillations.
I was kinda hoping there would be hammers. When faced with a giant metal sheet I generally think “hammers”. That’s why I’m not an invented instruments musician.
No. You’re right. Hammers is a clear oversight. Also squirt guns.
