In Western music

Beatboxing, an artform pioneered by rapper Doug E. Fresh, is one school of vocal percussion, originating in hip-hop music and often used to accompany rapping. it is utilized by many musicians spanning over a wide variety of genres.
In Indian music
Vocal percussion is also an integral part of many world music traditions, most notably in the traditions of North India (bols) and South India (solkattu). Syllables are used to learn percussion compositions, and each syllable signifies what stroke or combination of strokes the percussionist must use.
The art of speaking these syllables is called konnakol in South India, and traditional dance ensembles sometimes have a dedicated konnakol singer, although this practice is now waning. At one time it was a very respected art form, with many masters and singers.
In North India, the practice of reciting bols is usually limited to the percussionist reciting the composition about to be played, often in the context of a longer solo. These recitations are also sometimes spoken by a Kathak dancer.
In Japanese music
Kuchi shoga is the equivalent vocal percussion in Japanese music.
