Loop Labs is a site for creating music that I was familiar w/ but was reminded after reading a post on Free Technology 4 Teaachers. This is a site that is very similar to Garageband or Myna. All a user has to do is select a music track and instruments to create their song. Then by clicking on a music timeline they can hear what they recorded. The ability to add a voice is also available as well as sharing and download as an MP3.
I recommend checking out Loop Labs by clicking here!!
