A nocturne is a musical composition that is inspired by or evocative of the night. Typically, it is a short piece for piano, often characterized by a lyrical and expressive melody. The term is most commonly associated with the works of composers like Frédéric Chopin and John Field, who popularized the form in the 19th century. In visual arts, a nocturne can also refer to paintings that depict nighttime scenes. Artists such as James Whistler created works that capture the beauty and mystery of the night, often using soft colors and subtle lighting to convey a sense of tranquility and introspection.
