Chamber music occupies a significant place in the vast output of Bohuslav Martinu. His First Piano Quintet, written in 1933, a period during which Martinu renewed his interest in the folk-lore and traditional music of his native Bohemia, is a fine instance of the neo-classicism dominating his output in the 1930s. The larger-scale Second Piano Quintet, composed in 1944, exhibits the restlessness and anxiety that Martinu felt during the war years. The Sonata for Two Violins and Piano is freer and more relaxed than the two quintets, and is written in a style more baroque than classical.
