Composer.
Sergei Sergeyevich Prokofiev (23 April 1891 – 5 March 1953) was a Russian composer, pianist and conductor who mastered numerous musical genres and is regarded as one of the major composers of the 20th century. His best-known works include the March from The Love for Three Oranges, the suite Lieutenant Kijé, the ballet Romeo and Juliet – from which "Dance of the Knights" is taken – and Peter and the Wolf. Besides many other works, Prokofiev also composed five piano concertos, nine completed piano sonatas and seven symphonies.
