Sergei Vasilievich Rachmaninoff (Russian: \u0421\u0435\u0440\u0433\u0435\u0301\u0439 \u0412\u0430\u0441\u0438\u0301\u043b\u044c\u0435\u0432\u0438\u0447 \u0420\u0430\u0445\u043c\u0430\u0301\u043d\u0438\u043d\u043e\u0432; ; - 28 March 1943) was a Russian composer, pianist, and conductor. Rachmaninoff is widely considered as one of the finest pianists of his day and, as a composer, one of the last great representatives of Romanticism in Russian classical music.

Early influences of Tchaikovsky, Rimsky-Korsakov, and other Russian composers gave way to a personal style notable for its song-like melodicism, expressiveness and his use of rich orchestral colors.Norris, New Grove, 2nd. ed. , 707.

The piano is featured prominently in Rachmaninoff's compositional output, and through his own skills as a performer he explored the expressive possibilities of the instrument.
