The concertmaster of the Seattle Symphony Orchestra has been fired after 20 years at the helm, apparently at the behest of music director Gerard Schwarz. Ilkka Talvi, who has filed a grievance contesting his dismissal, was apparently the victim of a clause in the SSO musicians’ contract which allows the concertmaster to be dismissed at the will of the music director, even as the rest of the orchestra’s musicians are protected by a tenure system.
