Chopin's Berceuse in D-flat major, Op. 57 (1843) is a gentle, hypnotic lullaby built entirely over a quietly rocking tonic-dominant ostinato in the left hand, while the right hand weaves increasingly ornate melodic variations. It stands as one of Chopin's most refined and intimate piano miniatures, showcasing his mastery of embellishment and tonal nuance.
