I have been practicing beatboxing for 13 years, as well as teaching it to others for 5 years. Beatbox has its roots in hip-hop as a cultural phenomenon, but as an instrument it is also based on hundreds of years old voice techniques.
For me, beatbox is a tool with which to create music, experience trance through meditative sounds, as well as a means to explore the world of sound. Beatboxing can also be seen as a complex breathing exercise.
Beatbox is based on two sound categories – rhythmic – percussive, and melodic.
Melodic includes, for example, various throat singing techniques.
Beatbox can also be used in group improvisation, even without special previous experience, because the sounds used in beatbox can be understood through the pronunciation of letters and phrases.
