You can use Apple Loops to create an original song as a score for your movie. This process will take some experimentation to get right, but it allows you to set the exact tone and mood you want.
- With your GarageBand project open and Video Preview viewable, press Command-L to open the Loop Browser. When the Loop Browser opens, the Track Info pane automatically closes.
- To narrow the number of Apple Loops available, try typing “Guitars” into the search field.
- Click some of the items in the results list in the right column.
- Try selecting the loop “Acoustic Picking 06” and drag it to an empty area of the Timeline. Be sure to drag it all the way to the left so the loop starts at the beginning of the video. The loop is added to the Timeline and lasts for 8 seconds.
