After studying Musicology at the K.U.Leuven and the University of Berlin, Stephan Weytjens studied organ at the Lemmens Institute (LUCA School of Arts). He then worked as a researcher at the K.U.Leuven, where he wrote a doctoral thesis on Arnold Schoenberg's composition "Pierrot lunaire": "Text as a Crutch in Arnold Schoenberg's "Pierrot Lunaire" op. 21? An Analysis of the Relationship between Textual Aspects and Musical Structure in Free Atonality," Leuven: K.U. Leuven, 2003.
This doctoral dissertation has since been cited in quite a few authoritative international publications including "The Cambridge Companion to Schoenberg" (Cambridge University Press, 2011) and Jack Boss' "Schoenberg's Atonal Music" (Cambridge University Press: 2016).
Stephan Weytjens has published articles in international professional journals and has lectured at international musicological conferences in Vienna (Arnold Schoenberg Center), Paris (Université de Paris-Sorbonne) and New York City (Mannes Institute for Advanced Music Studies, NYC), among others.
He is co-author of the book publications "Tempo and Time in Contemporary Music" (Leuven: Acco; 2007), and "Trompe l'oreill. Researching Innovative strategies towards 'illusive' sound-process composition", (Leuven: Acco, 2014).
He also regularly writes program texts for deSingel, gives concert introductions, is still active as an organist, and accompanies music and culture tours for the organization Cimarosa (including to the Bachfest Leipzig, Festival Thüringer Bachwochen, Innsbrucker Festwochen der Alten Musik, Berlin, Dresden, Copenhagen, London, Edinburgh and New York).
Stephan Weytjens teaches Music History, Music Analysis and Music Writing at the Royal Conservatory of Antwerp.
