To paste a region:
 Move the playhead to the point in the timeline where you want the region to start,
then choose Edit > Paste.
When you paste a region, the playhead moves to the end of the pasted region. You can
paste additional copies of the region, and each one starts at the point in the timeline
where the previous one ends.
Moving Regions
You can move a region by dragging it to a new point in the timeline. You can also
move a region to another track of the same type as the region. (Real Instrument
regions can be moved only to Real Instrument tracks, and Software Instrument regions
can be moved only to Software Instrument tracks.)
To move a region:
 Drag the region left or right to a new point in the timeline.
 Drag the region up or down to another track of the same type.
As you move a region, alignment guides appear showing you when the left or right
edge of the region is aligned with other objects in the timeline. If you don’t want to use
alignment guides, you can turn them off in the General pane of GarageBand
preferences.
You can also move regions left to fill the space of a deleted region.
To delete a region and move the following regions left:
1 Select the region you want to delete.
2 Choose Edit > “Delete and Move.”
All following regions on the same track move left by the length of the deleted region.
Two regions cannot overlap in the same track. If you drag a region over part of another
region, the region being covered is shortened to the edge of the overlapping region. If
one region completely covers another region, the region being covered is deleted from
the track.
Try adding a new drum or bass loop to the timeline, and then loop it to create a new
rhythmic groove.
