Many groups utilize music to focus emotional energy on themselves.
For example, churches use music to concentrate the emotional energy of their members on the church. As they sing their hymns, fantasies awaken in the minds of church members illustrating the ideas they believe in. Month after month, year after year of recreating their religious images in songs causes these fantasies to have great power and to become very vivid. In the same way, countries employ national songs to direct the vision of their citizens. Music has a magical effect on people and their social groupings.
