Josef Suk’s Piano Quartet (1874 1935) quickly became a standard work not least as a result of the extensive concerts given by the Bohemian Quartet in which Suk was second violinist. This is however the first scholarly-critical edition of this work. It is based largely on a revision of the first edition which contains Suk’s alterations of 1914 and appeared in 1924 on the first copy as well as on newly discovered copies of the parts. Valuable information has also been extracted from printed parts of which the original copies are now no longer extant.
