Johannes Brahms was a German composer and pianist, and one of the leading musicians of the Romantic period. Born in Hamburg, Brahms spent much of his professional life in Vienna, Austria, where he was a leader of the musical scene. In his lifetime, Brahms' popularity and influence were considerable; following a comment by the nineteenth-century conductor Hans von Bülow, he is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the Three Bs. Brahms composed for piano, chamber ensembles, symphony orchestra, and for voice and chorus. A virtuoso pianist, he premiered many of his own works; he also worked with some of the leading performers of his time, including the pianist Clara Schumann and the violinist Joseph Joachim.
