Thomas van Dun (The Netherlands, 1995) is a contemporary composer and songwriter. He has written for diverse ensembles including multiple symphony orchestras.

His work for classical ensembles is distinguished by rhythmical vividness, its ties to electronic dance music, colourful use of instrumentation, and grand spatial gestures. Recurring themes within his music is the duality of the sublime – highlighting the interaction between melancholy ecstasy – as well as existentialism and spiritualism. His pieces have been played by orchestras such as the Nederlands Studenten Orkest, the Radio Filharmonisch Orkest, the Residentie Orkest. In 2018, the inauguration for the Olympic Games of 2018 featured his music. In August of 2021, his percussion concerto In Transit premiered during the 2021 edition of the Nederlands Studenten Orkest concert series, with Nederlandse Muziekprijs winner Dominique Vleeshouwers as the soloist. In 2022, he created a concert experience ‘Light Mass’ for festival Dag in de Branding, as artist-in-residence. In October 2023, his new piece ‘Rocailles de l’après-vie…’ will mark his debut at the NTR ZaterdagMatinee in the Concertgebouw Amsterdam with Asko|Schönberg and Bas Wiegers.

Van Dun has studied with composers such as Martijn Padding, Yannis Kyriakides, Dai Fujikura, and Calliope Tsoupaki at the Royal Conservatoire of The Hague and the Royal College of Music in London.
