Beatboxers synthesize percussion through vocal folds that are not percussion instruments
Evidence
Producing a convincing percussive sound is a nontrivial task, since it is being synthesized acoustically using the vocal tract, which itself is not a percussion instrument. On the other hand, the fact that the percussive sounds are emanating from the vocal tract means that the continuity illusion for the words works better than it would otherwise. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1660
