Real-Time Magnetic Resonance Imaging was used to examine mechanisms of sound production in an American male beatbox artist. The subject's repertoire was found to include percussive elements generated using a wide range of articu- latory con 12;gurations, and three of the four airstream mechanisms normally ob- served in human speech production: pulmonic egressive, glottalic egressive, and lingual ingressive. In addition, pulmonic ingressive production were observed, which appears to be used strategically as a means of managing breathing during extended beatbox performance. The data offer insights into the paralinguistic use of articulatory gestures, and the ways in which they are coordinated in musical performance.
