Frédéric (or Fryderyk) Chopin (1810 – 1849) was a celebrated Polish composer and virtuoso pianist of the Romantic period. His piece Nocturne Op. 9 No. 2 is one of his most popular compositions, which he composed when he was around twenty years old. It is a very melodic piece that uses repetitions, and, together with two other nocturnes in the series, was dedicated to Belgian concert pianist Marie Pleyel.
