Fosse d'Orchestre (orchestra pit) is a sculptural orchestration at the Canal de St. Martin in Paris. :  Underwater speakers project sound on the water surface,into turning it into a sensitive membrane and resonant body. 

Fosse d’Orchestre was adapted for the Setouchi Triennale in 2019 where six speakers were placed in an olive grove, infusing the space with island sounds, the voices of people at work at the local factory, the humming of factory machinery, and interviews.
