In 2009, there were approximately 137,000 court-involved minor children in residential detention and rehabilitation facilities in the United States as a result of committing a crime. Most of these children have no opportunity to participate in music education while serving long-term sentences in residential lockdown.

This article describes a model program for music education in this setting and explores the positive changes in attitude and behavior that occur for these students as a result of music participation. Included are recommendations for starting music programs in residential juvenile detention facilities.
