Berceuse is a French world for lullaby, or cradle song. In classical music, a berceuse is a lullaby-like piece of music. A famous berceuse is Frédéric Chopin's berceuse for solo piano, opus 57. Perhaps the most famous berceuse of all time (though it is called a lullaby) is Brahms' song Wiegenlied.

Typically a berceuse is in triple meter, or in a compound meter such as 6/8. Tonally most berceuses are simple, often merely alternating tonic and dominant harmonies: since the intended effect is to put a baby to sleep, wild chromaticism would be somewhat out of character. Another characteristic of the berceuse--for no reason other than convention--is a tendency to stay on the "flat side" --for example the berceuses by Chopin, Liszt and Balakirev are all in Db.

Other famous examples of the genre include the piece by Maurice Ravel for violin and piano, Berceuse sur le nom de Gabriel Fauré; the Berceuse élégiaque by Ferruccio Busoni; and the Berceuse by Igor Stravinsky which is included in the Firebird ballet.
