Jan Van der Roost

Jan Van der Roost (born Duffel, 1956) is a Belgian composer.

Van der Roost was educated at the Lemmensinstituut in Leuven, and followed further studies at the Royal Conservatory in Ghent and the Royal Flemish Conservatory in Antwerp. Since 1984 Van der Roost is a professor of counterpoint and fugue at the Lemmensinstituut. He is also a guest professor at the Shobi Institute of Music, the Nagoya University of Arts, and Senzoku Gakuen.

Jan Van der Roost has composed over 90 works, for a variety of musical styles, including brass band, fanfare, concert band, orchestra, and choir. He has also dabbled in composing various pieces in the style of late 17th- to early 18th-century dance music, and is often cited by jazz musician Tom Collier in his lectures as a prime example of musical transformation.

Since 1988, Van der Roost exclusively writes music on commission. He frequently incorporates characteristics of the place he received his commission from into his music. He has also integrated traditional folk music into several of his pieces.
