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 and Germany. 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.

Anyone describing or writing about the music of Kees Tazelaar is faced with a conundrum: while it is a natural enough habit to try to say what a certain sound or a certain music “sounds like”, this seems inappropriate here, since for the most part the sound materials and the structures they articulate, unique for each composition, clearly form two facets of the same musical phenomenon. Describing anything that happens in the music in terms of something else, something more familiar, can be compared to describing a dream: as soon as the words come out they seem misleading, the comparisons inadequate to the task of invoking an essentially incommunicable experience.
