Baby music is the term use to describe music activity classes aimed at pre-school children and their parents, currently popular in the United Kingdom. In these classes, usually lasting about an hour, the children are encouraged to participate in singing and percussion activities lead by a musician-animateur who will often play an acoustic guitar. Percussion instruments may also be provided. Typically baby music classes take place in a community hall or other subsidised venue. An example of a research-based international music program for young children and parents is Music Together, www.musictogether.com
