electromechanical artist david cranmer of nervous squirrel studio debuts his massive 44-note ‘ore-some xylophone’ as part of trinity college’s science gallery sound check exhibitionthe sculpture is played mechanically by a series of mallets and actuators, which are part of a machine responsible for moving or manipulating a mechanism or system. additionally, the design contains a geiger counter mounted underneath a lump of uranium ore, hence the name ‘ore-some’ xylophone.

nervous squirrel‘s ore-some xylophone features a handwheel that can be used to move a sliding lead shield, which causes the detected activity to increase when the geiger-müller tube is exposed to the rock. the detected radioactive events are then used to create a composition using solenoids and mallet mechanisms to play the xylophone. after the first three clicks are counted, the time between clicks one and three is mapped across the total range of 44 notes, and click two determines the note to be played within that range. when the next click is detected, two and four become the total range, and three becomes the next selected note. it is impossible to predict when the next radioactive event will occur, and so the music generated is truly random.

the random timings are converted to MIDI notes before being sent to the mechanism control circuitry

the sculpture stands around 2.7 m high, and weighs 140 kg

each mechanism had to be slightly different, so that the arc of the mallet met the centre of the block

the enclosure is made of thick aluminium plates to withstand use from thousands of visitors who will interact with the sculpture
