Tim Hawkinson is an interesting figure to feature here. He Is known for building only one instrument and that is the Überorgan. The Überorgan is a sculpture he built that functions like a roll operated piano and plays music on a bagpipe like instrument. The scale of the instrument is enormous, separating out many of its sound making components across separate rooms and architectural spaces. The instrument is mostly built out of plastic sheeting that has been inflated like a large balloon. The instrument functions are a sound sculpture.
