Most likely a blown fuse. But, the horn itself can be defective.
It it either a blown fuse, defective horn, bad ground, or defective horn switch. Check the fuse, if it is blown, replace, if it is good, run a wire to the horn directly from the battery. If the horn blows, suspect a bad horn switch.
look in your fuse panel for a fuse labeled HORN..pull it out and see if it is blown (broken)
You have a loose wire, blown fuse or a faulty horn.

The most common horn problems are either a blown fuse or a bad horn relay. Both should be located under the hood in the fuse box.
check the fuse to make sure it has not blown out
Blown/no fuse, bad relay, or a bad switch
