Human Beat Box
Beatboxing, aka vocal percussion, is primarily concerned with the art of creating beats and rhythms using the human mouth. However, it also involves the imitation of sounds such as scratching. 'Vocal percussion' is more commonly associated with a-cappella and rockapella groups, whereas 'beatboxing' and 'human beatbox' are terms usually associated with hip hop or other urban music genres. 'Multivocalism' is a relatively new term, coined by the UK's Killa Kela.
