Virgil Moorefield (born August 9, 1956) is a composer and intermedia artist based in Rüschlikon, Switzerland.

By the time he was ten, he spoke three languages fluently, the result of having gone to public elementary schools in Italy, the United States, and Switzerland.

In 1979, Moorefield moved to the East Village of New York City and began a career as a composer, teaching himself along the way.

In the early Nineties, he led a nine-piece group that performed meticulously notated avant-rock in Europe and the U.S.[4] For performances at various festivals in the mid-Nineties [5] as well as on his Tzadik Records release,[6] Moorefield experimented with a loosely structured hybrid between compositional and improvisational processes, coining the term "comprovisation" to describe his work of that period.

In 2013 he released a DVD of a large scale piece performed on three continents, "Five Ideas About the Relation of Sight and Sound".
