A good song needs an introduction to set the mood before it gets going. An introduction also creates anticipation, and gives the listener a chance to tune in before the main part of the song starts.
You can create a simple introduction for your song by letting the drums play alone for a couple measures before the rest of the song starts.
Choose Split from the Edit menu to create regions in loops that you can move around or remove. Remove regions from all but one track to break down your song, and leave just one instrument playing for a while.
Choose Join from the Edit menu to join multiple regions into a single region. To be joined, the regions must be adjacent to each other and on the same track, with no space between them.
