Vinko Globokar is a French-Slovenian avant-garde trombonist and composer. He studied composition with Luciano Berio and Karlheinz Stockhausen and was influenced by Mauricio Kagel, a composer of instrumental theater pieces known for his unorthodox use of instruments to create a variety of sounds. Globokar's music focuses on creativity and free improvisation, with a heavy emphasis on the performer and their interpretation of the piece. Many researchers consider ?Corporel to be a protest against what he called "Badabum", the idea that one instrument can only make one sound, which lead composers to add a new instrument to their pieces every time a new sound was needed rather than figuring out how to get new sounds out of the instruments already being used. Globokar asserted that every instrument can make more than one sound, even if those sounds aren't natural for the instrument, and he argues this point in ?Corporel by writing an entire piece that uses only the performer's body and voice as the instrument.
