- Tropical Fish Opera : for 4 performers
As with Robert Moran’s ‘Divertissement no. 1,’ , Sender wasn’t necessarily thinking about the notation as ‘animated,’ but simply a novel way to accomplish ‘some’ thing. The performance and setup instructions are quite detailed, including recommended aquarium size, fish selection, the importance of heating, and how to READ the fish. Sender’s instructions can be found here, along with a short review from a mid-1970s performance.
