Frédéric Chopin (1810-1849) was a Polish composer and virtuoso pianist, primarily known for his contributions to the Romantic era of classical music. His works predominantly focus on the piano, showcasing intricate melodies and innovative harmonies. Chopin's compositions often reflect his Polish heritage, infusing elements of folk music and dance. Notable works include his "Nocturnes," such as Nocturne in E-flat Major, Op. 9, No. 2; "Ballades," particularly Ballade No. 1 in G minor, Op. 23; and "Etudes," like the famous "Revolutionary Etude" in C minor, Op. 10, No. 12. His "Preludes," especially Prelude in D-flat Major, Op. 28, No. 15 ("Raindrop Prelude"), are also widely celebrated.

His lyrical style and emphasis on personal expression paved the way for future Romantic composers, solidifying his reputation as one of the greatest composers of piano music in history.
