Sergei Rachmaninoff was a Russian composer, pianist, and conductor, born on April 1, 1873. He is known for his romantic style of music, which combines rich harmonies and expressive melodies. Rachmaninoff's most famous works include his Piano Concerto No. 2 and Rhapsody on a Theme of Paganini, both celebrated for their emotional depth and technical challenges. Rachmaninoff faced significant challenges during his early career, particularly after the 1917 Russian Revolution, which led him to emigrate to the United States. Despite these difficulties, he became a prominent figure in the world of classical music, influencing many musicians and composers with his unique style until his death on March 28, 1943.
