The Matter of Sound
The sound of material in six parts: wooden, metal, glass and stone bars of the same shape, fabric and paper textures, water. At the end a blind test: 'Which material?' Synthesised on the device, not recorded; there is no claim of any effect.
Why this order? In the first four parts the shape is fixed: the same free bar, modes in the ratio 1 : 2.756 : 5.404, in three sizes. Only the material changes, that is, the internal friction: metal rings for seconds, glass for less, wood is short and dull, stone hardly rings at all. In each part first the sizes one by one, then in turn, then rubbing. In the fifth part the ringing disappears entirely: fabric, paper, a brush and a rainstick are the noise of friction and grains. The last part is water: a stream and the same rain changing on three surfaces; finally a blind test.
