Johannes Brahms was a German composer and pianist. Born in Hamburg into a Lutheran family, Brahms spent much of his professional life in Vienna, Austria. In his lifetime, Brahms's popularity and influence were considerable. He is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the "Three Bs", a comment originally made by the nineteenth-century conductor Hans von Bülow.
Brahms composed for piano, chamber ensembles, symphony orchestra, and for voice and chorus. A virtuoso pianist, he premiered many of his own works; he worked with some of the leading performers of his time, including the pianist Clara Schumann and the violinist Joseph Joachim (the three were close friends). Many of his works have become staples of the modern concert repertoire. Brahms, an uncompromising perfectionist, destroyed some of his works and left others unpublished.
