Music is considered a universal language and it encourages working together with other people. In the case of English acquisition, it helps in the development of the language. Having a large repertoire of songs helps enrich vocabulary and exposes the children to grammatical structures. It also offers information about other cultures.
The accompaniment of body movements while singing a song helps the child to remember the songs more easily.
