Ivar is a Dutch clarinet player who has enjoyed an extraordinary international chamber music career. With the Calefax Reed Quintet, he performed for thirty-three years in leading concert halls and at some of the most beautiful festivals in the world. As a musician, Ivar has become a very experienced listener. That is the skill he uses and continues to develop as he follows his current path, coaching teams and ensembles. Working especially with young professional musicians, Ivar guides the process of artistic development. He is almost uniquely qualified to shed light on the ways individual performers can negotiate group dynamics in order to form an ensemble that is capable of distinguishing itself in a way that is both natural and convincing. Ivar teaches at the Utrecht Conservatory and tutors at the Amsterdam String Quartet Biënnale.
