GarageBand is a software application that allows users to create a piece of music. It is developed by Apple Computer for Mac OS X.
The application is not aimed at professional musicians, but it is intended to help amateurs produce music easily. The application comes with 1,000 pre-recorded sampled loops, and 50 sampled or synthesized instruments which can be played using a MIDI keyboard connected to the computer, or using an on-screen keyboard.
