Nocturne (painting) in the context of "American Old West"

The depiction of night in paintings is common in Western art. Paintings that feature a night scene as the theme may be religious or history paintings, genre scenes, portraits, landscapes, or other subject types. Some artworks involve religious or fantasy topics using the quality of dim night light to create mysterious atmospheres. The source of illumination in a night scene—whether it is the moon or an artificial light source—may be depicted directly, or it may be implied by the character and coloration of the light that reflects from the subjects depicted. They are sometimes called nocturnes, or night-pieces, such as Rembrandt's The Night Watch, or the German Romantic Caspar David Friedrich's Two Men Contemplating the Moon of 1819.

In America, James Abbott McNeill Whistler titled works as nocturnes to identify those paintings with a "dreamy, pensive mood" by applying the musical term, and likewise also titled (and retitled) works using other music expressions, such as a "symphony", "harmony", "study" or "arrangement", to emphasize the tonal qualities and the composition and to de-emphasize the narrative content. The use of the term "nocturne" can be associated with the Tonalist movement of the American of the late 19th century and early 20th century which is "characterized by soft, diffused light, muted tones and hazy outlined objects, all of which imbue the works with a strong sense of mood." Along with winter scenes, nocturnes were a common Tonalist theme. Frederic Remington used the term as well for his nocturne scenes of the American Old West.
