Marianthi Papalexandri-Alexandri Sound Instrument/ Installation/ Sculpture

Materials: motors, acrylic glass, nylon line, silicone. 2010

Untitled II is a work adaptable to any space that can be presented both as a sounding sculpture and as an instrument in the context of a solo live performance. Untitled II consists of seventeen clear acrylic cylindrical tubes with one end open and the other closed with an elastic silicone membrane. A nylon line is fastened through a hole at the centre of the membrane; the end of the nylon line is loosely secured in an acrylic resined motor driven rod to produce friction. The sound is produced by the nylon line causing the membrane to vibrate by friction. The sound of Untitled II can be influenced by manipulating the tension of the nylon lines, changing the speed of the motor, turning on and off the motors or by depressing the membrane with the fingers while it is vibrating to vary the pitch.
Untitled II creates and explores a soundscape of machine- produced long sustained sounds and textures with organic character and without any post processing. Furthermore it questions the role of the performer highlighting the difference between performing and operating ( “music as art” and “music as music”).
