Herman Muntzing attended the Royal Academy of Music in the late eighties, transforming from a straight jazz/rock bass player into a more broad-minded sound artist, working mainly in the fields of improvised and experimental music.

Since the late nineties, his life as a musician includes different Swedish and international groups, playing in Sweden, Denmark, Norway, UK, Iceland, Belgium, France, and Holland. He has collaborated with Phil Minton, Eugene Chadbourne, Martin Küchen, Andreas Axelsson, Peter Nilsson, Dror Feiler, Rex Caswell, Sten Sandell, Mats Gustavsson, Raymond Stridh, Johannes Bergmark, Stefan Östersjö, Amit Sen, Kjell Nordesson,

He works and lectures on creative sound research, graphic notation, and building experimental musical instruments, seeking to expand the common thoughts about the qualifications for a "real" musical instrument. His research led to the Flexichord, a 12-stringed instrument with pickups from two electric guitars attached to a horizontal solid piece of wood, which is played with prepared objects and using rubber, stones, glass, metal, sawblades etc. This he combines in performance with electronics and sampling.
