pendulum sound machine
by kouichi okamoto

(the musical instrument) subverts a record player's rotation to make noise with 16 plate-hitting pendulums. the brass-plated pendulums rest on original phonograph record with no grooves, and as the record turns, the pendulums move and hit the plates overhead. multiple machines can be used in tandem, creating different tones with plates of various sizes.
