Frédéric Chopin (1 March or 22 February 1810 – 17 October 1849) is widely considered one of the greatest Romantic piano composers. A renowned child-prodigy pianist and composer, he grew up in Warsaw and completed his music education there; he composed many of his mature works in Warsaw before leaving Poland in 1830 at age 20. During the remaining 19 years of his life, Chopin gave only some 30 public performances, preferring the more intimate atmosphere of the salon; he supported himself by selling his compositions and teaching piano. After some romantic dalliances with Polish women, from 1837 to 1847 he carried on a relationship with the French writer Amandine Dupin, aka George Sand. For most of his life Chopin suffered from poor health; he died in Paris in 1849 at age 39. The vast majority of Chopin's works are for solo piano. Chopin invented the instrumental ballade and made major innovations to the piano sonata, mazurka, waltz, nocturne, polonaise, étude, impromptu, scherzo and prélude.
