The Nocturnes, Op. 37 are a set of two nocturnes written and published by Frédéric Chopin in 1840, though it is thought that the Nocturne in G major, Op. 37, No. 2 was composed in 1839 around the time of his stay with author George Sand in Majorca.Unusually, neither piece carries a dedication.

The Nocturne in G minor is initially marked as andante sostenuto and is in 4/4 meter. In measure 41, the key changes to E-flat major and returns to G minor in measure 67. The piece is a total of 91 measures long, ending with a Picardy third, and is in ternary form. One of Chopin's students once claimed that Chopin himself forgot to mark the increase in tempo for the chorale, which led to the section being played too slowly.
Performer:Arthur Rubinstein.
