About the timeline

The timeline is where you build the arrangement of your project.

The timeline contains rows called "tracks." Each track extends from the beginning to the end of the project. A GarageBand project can have two types of tracks:

At the top of the timeline is the beat ruler, which shows beats and measures, the units of musical time. You can visually align items in the timeline with the marks in the beat ruler. You can also use the timeline grid to precisely align items in the timeline with beats and measures in the beat ruler. You can also scroll to see other parts of the timeline, and zoom in for precise editing or zoom out to see more of the project.

The playhead is the line running vertically through the timeline, and shows the point in the project currently playing.
