Kees Tazelaar (*1962) followed courses in Sonology in Utrecht and The Hague, and later studied composition under Jan Boerman at the Royal Conservatoire. He has been teaching at the Institute of Sonology since 1993 and has been head of the institute since 2006. 
His electronic music features a combination of formalisation, richness of sound and a compositional approach to sound spatialisation.
Compositions have been commissioned by the Performing Arts Fund NL, Johan Wagenaar Stichting, Festival in de Branding, Hollandia, De Veenfabriek, Festival Relevante Musik Berlin, and Groupe de Recherches Musicales Paris.
As well as a composer, Kees Tazelaar is a historian, who has specialised in the early years of electronic music in the Netherlands. He has twice been the Edgard Varèse Guest Professor at the Technische Universität Berlin, where he earned his PhD in 2013 with the dissertation On the Threshold of Beauty: Philips and the Origins of Electronic Music in the Netherlands 1925–1965 (Rotterdam: V2_Publishing, 2013).
Kees Tazelaar was awarded a Fellowship Residency from the Bogliasco Foundation in 2017.
