Thirteen Strings

Thirteen Strings is a chamber orchestra in Ottawa, Ontario, Canada. It was founded in 1976 by Brian Law, then conductor of the Ottawa Symphony Orchestra, who led the ensemble until 1991. Its initial members were drawn from the National Arts Centre Orchestra. After Law left in 1991, various guest conductors directed the ensemble, including Calvin Sieb. Jean-François Rivest was the Artistic Director from 1999 to 2006. The Artistic Director in 2012 was Kevin Mallon. The performances are often supplemented by vocal or instrumental soloists. The ensemble performs in such venues as St Andrew's Presbyterian Church and Dominion-Chalmers United Church.

Thirteen strings also organizes Junior Thirteen Strings, which consists of Ottawa region string players aged 12–17 selected to play with the Thirteen Strings in a concert during their regular season.
