Antonín Leopold Dvořák (September 8, 1841 ? May 1, 1904) was a Czech composer of Romantic music. He successfully combined melodies of a folk idiom with symphonic and chamber music. Dvořák wrote in a variety of forms: his nine symphonies generally stick to classical models that Beethoven would have recognised, but he also worked in the newly developed symphonic poem form and the influence of Richard Wagner is apparent in some works. Many of his works also show the influence of Czech folk music, both in terms of rhythms and melodic shapes; perhaps the best known examples are the two sets of Slavonic Dances. Dvořák also wrote operas (the best known of which is Rusalka); chamber music (including a number of string quartets, and quintets); songs; choral music; and piano music.
Dvořák's works were catalogued by Jarmil Burghauser in Antonín Dvořák. Thematic Catalogue. Bibliography. Survey of Life and Work (Export Artia Prague, Czechoslovakia, 1960). In this catalogue, for example, the New World Symphony (Opus 95) is B178.
