″Music on a Long Thin Wire" is a musical piece by Alvin Lucier conceived in 1977.
The ends of the wire are connected to the loudspeaker terminals of a power amplifier placed under one of the tables.
Wooden bridges are inserted under the wire at both ends to which contact microphones are embedded, routed to a stereo sound system.
The microphones pick up the vibrations that the wire imparts to the bridges and are sent through the playback system.
