Frédéric Chopin Nocturne Op. posth. in C sharp minor

Frédéric Chopin was a renowned Polish and French composer who published his first composition at age 7 and began performing one year later. In 1832, he moved to Paris, socialized with high society, and was known as an excellent piano teacher. Frédéric Chopin is famous for his expressive piano playing and the innovative works he composed for that instrument. His piano compositions were highly influential during his time.

Frédéric Chopin wrote 21 nocturnes (named after the French which meant nocturnal, from the Latin word: "Nocturnus") for solo piano between 1827 and 1846, of which this is the final (twenty-first). These nocturnes are generally considered among the finest short solo works for the instrument and hold an important place in contemporary concert repertoire. Although Chopin did not invent the nocturne, he popularized and expanded on it, building on the form developed by Irish composer John Field.
