GarageBand offers a very powerful yet easy to use digital music studio that can be used to teach in class and for use, in practice, by students anywhere.
Apple provides GarageBand for free on most of its hardware, including Mac, iPad, and iPhone -- and lets you jump between devices if you're using iCloud to store the work. Crucially, this is a platform that lets you create music, with virtual instruments, from scratch or with pre-built loops and more.
