Does GarageBand have rhythms to choose from (like it has instruments to choose from) - background rhythms for when the melody line is being played

Question

Does GarageBand have rhythms to choose from?  Like it has instruments to choose from.  Examples: waltz, jazz, country, rock, rap, etc.  So when I'm playing my melody line I can choose a rhythm that will do a sort of background sound.  And that can be changed up sometimes (I hit a button on my electric keyboard when the rhythm is playing and it makes a sort of change up)

You build the rhythm track by dragging loops from the Loop Browser. The loops come in families, so you can vary  the pattern; there are basic loops and fills to make transitons. Loops will automatically adapt to the tempo and key of your project.
You can filter the selection of loops in the loop browser by setting tags, like "relaxed" or cheerful, for example to find jazzy drumsets, set the loop browser like this:
