The speed of change in electronic media in the latter part of the 20thcentury revolutionised access to and the use of music in people’s lives. Music can be accessed in many ways, through radio, CDs, DVDs, TV, tablets, SMART technologies, computers and phones, and can be downloaded to enable the creation of personal playlists. This can be achieved with very little effort, but this was not always the case. Historically, people could only access music through participating in religious or other social events. These changes have made it possible for individuals to use music to manipulate their moods, arousal levels and feelings, and create environments which may change the way that other people feel and behave. Music can be used to aid relaxation, overcome powerful emotions, generate moods appropriate for carrying out routine activities, prepare for social activities or stimulate concentration. In short, music can be used to promote wellbeing. In young people, it supports the development of identity and self-presentation.
