As a rule, musicians are members of the BSO vzw/asbl. Only occasionally the orchestra is reinforced with external musicians, depending on the specific needs of the projects and temporary unavailabilities.

All relevant sections of the symphonic orchestra are represented: first violins, second violins, violas, cellos, double bass, woodwinds, brass, percussion and harp.

Musicians are accepted in the orchestra if vacancies open up and after successfully passing an audition. Applications can be made by sending an e-mail with relevant details to
