In some societies this is recognised and attempts are made to control music by those in power. Music is powerful at the level of the social group because it facilitates communication which goes beyond words, induces shared emotional reactions and supports the development of group identity Music is powerful at the individual level because it can induce multiple responses - physiological, movement, mood, emotional, cognitive and behavioural. The brain's multiple processing of music makes it difficult to predict the particular effect of any piece of music on any individual. Music has powerful therapeutic effects which can be achieved through listening or active music making. Music can promote relaxation, alleviate anxiety and pain, promote appropriate behaviour in vulnerable groups and enhance the quality of life of those who are beyond medical help.
Music can play an important part in enhancing human development in the early years.
Active involvement in music making in children may increase self-esteem and promote the development of a range of social and transferable skills. People can use music in their lives to manipulate their moods, alleviate the boredom of tedious tasks, and create environments appropriate for particular social events. The easy availability of music in everyday life is encouraging individuals to use music to optimise their sense of well-being. Music can influence our behaviour in ways which are beyond our conscious awareness. Knowledge of these effects can be used to manipulate our work and purchasing behaviour.
