Timeline

From Guide

After you create your riffs using the Riff Timeline:

You can drag them into the Song Timeline above the grid, serially, so that the riffs you select play one right after another. The Song Timeline has its own play button; click on the layer time button, and playback jumps over to playing the current riff.

So now you have your riffs arranged to make a song.

There is a Songlayers Timeline as well. You can record Songlayers, in other words, tracks (layers) that go for the length of the song. This would be a good choice for doing a lead part over your riffs, adding a vocal, or whatever you want to do that lasts the length of the song. The Songlayers Timeline does not loop.
