Percussionists percuss, which is an improvement over the usual cussing that drummers do.
Percuss is once per beat. But a scat singer is better than that as they can also syncopate. You just can't tell if what they are singing is actually cussing. It probably is in at least one language, living or dead, so you will be offending at least someone with your jazz, even if it is only an Etruscan or Klingon.
