The Tu-Yo Afrika is a new instrument that uses pneumatics, acoustics and informatics to generate a continuous vibration of a latex membrane stretched across the end of an aluminum tube. A small black rubber ball placed inside the tube bounces randomly, stimulated by the acoustic vibrations of the membrane. Its bouncing generates a kind of rhythmic “drone” whose figures are constantly rearticulated and renewed, creating a “hypnotic” ambience.
