The report explains the results of exploratory research into the work of the prison based charity Changing Tunes, which uses music both within and also outside prison with offenders and ex offenders. Evidence revealed that the pro social impact on the participants came as a result both of participation in music and the roles this gave them but also as a result of longevity of the support and mentoring from Changing Tunes staff which continued both inside and outside prison.

"If participants could be said to become “addicted” to the work of Changing Tunes, this addiction was a purely healthy one, based on a love of learning, personal growth and achievement."
