A lullaby is a soothing piece of music, usually played or sung to young children. The purposes of lullabies vary. In some societies they are used to pass down cultural knowledge or tradition. In addition, lullabies are often used for the developing of communication skills, indication of emotional intent, maintenance of infants' undivided attention, modulation of infants' arousal, and regulation of behavior.

Lullabies can be found in many countries, and have existed since.
