The Martinů Quartet (Czech: Kvarteto Martinů) is a Czech string quartet ensemble founded in 1976, originally under the name Havlák Quartet by students of Professor Viktor Moučka at the Prague Conservatory. In 1985, with the approval of the Bohuslav Martinů Foundation, the quartet assumed its present name Martinů Quartet, pledging to promote the chamber music of Czech composer Bohuslav Martinů. The quartet specialises in the works of Czech composers such as Smetana, Dvořák and Janáček, and especially the works of Bohuslav Martinů. They perform regularly at the Prague Spring Festival as well as concerts in many European Countries, the United States, Canada and Japan. The quartet also teaches chamber music performance at two annual chamber music workshops in the Czech Republic, which are open to both amateur and professional musicians.
