Beatboxing
Beatboxing is making percussive noises with the mouth, lips, tongue and voice. Performers try to imitate the sounds of a drum machine. They could also try to imitate turntablism and other instruments. It is used a lot in hip-hop music. This includes the use of humming, singing and tapping.
