GarageBand is a music application that comes bundled with Mac computers. It allows users to create, record, edit and share their own music. While some may think "real" musicians don't use GarageBand, famous songs like Rihanna's "Umbrella" have been created using it. GarageBand can be used in classrooms for projects like creating original music for movies or podcasts, recording class lectures, or teaching students how to play instruments.
