Frédéric Chopin finished and published his set of two Nocturnes, Op. 37, in 1840. It has been suggested that the nocturne no. 2 was written in 1839 during the composer's stay in Majorca. In any case, this set of pieces had a very warm reception, though its popularity has waned over the course of the last century. They have been considered as a sort of transition (in terms of style) between Opp. 27 and 32. Unusually, neither piece carries a dedication.
