Music of the Polygonola – Applied Vibro-Acoustics
Back in stock, released in 2017
An analogous phenomenon is captured in carefully designed two-dimensional metal plates cut in the shape of various polygons. The size and thickness of the plates are chosen to reproduce a particular set of overtones, which differ from the conventional twelve-tone equal temperament scale. The sounds generated in these polygonola differ from those of a one-dimensional string because the instrument is approximately two-dimensional and sustains two-dimensional waves. The sounds generated also differ from the membrane of a drum, as the membrane is supported at its perimeter but the polygonola is supported at selected interior points, resulting in different overtones when struck in the center and edge of the instrument.
