winfried ritsch: mono metal space

Winfried Ritsch on Mono Metal Space: "... a 2x1m metal plate hung on a stand or frame is stimulated by amplifier driven modified motors used as strong transducers, and sensored by pickups. The computer-controlled feedback uses digital filters and dynamics effects as signal processing to try to resonate the plates within their individual overtones. These playable feedback filters are controlled as notes by playing increasing and decreasing sounds near the composed frequencies of the notes which evokes speech and 'singing-like' musical phrases in a wide range of frequencies typical of the chosen material. As a result of this arrangement, normally barely detectable resonances are produced in the musical space and create metallic-sounding multi-tonal clusters, whereby, due to the formation of formants and noise between the shifts, fast phrases and extremely slow polyphonic chords emerge from the sound plate. What initially appears as chaotic movements can soon be experienced as structured recurring patterns..." Personnel: Winfried Ritsch - composition/concept.
