A late miniature by Liszt, evoking deep sorrow and possessing religious overtones.

In his later years, Liszt continued to experiment, attempting to depart from tonality by employing unique scales and harmonies. This piece, Nuages gris (Grey Clouds), like Bagatelle sans tonalité (Bagatelle without Tonality), is one such experimental work. It possesses an avant-garde style, seemingly anticipating later atonal music.

True to its title, the entire piece is filled with a somber atmosphere.

Composed in 1881, it was published in 1927.
