Trondheim Symphony Orchestra & Opera consists p.t. of 85 musicians in fulltime employment. In addition to symphonic concerts, which is the main activity, TSO has developed particularly varied and versatile additional activities. TSO produces opera in Trondheim, and we give special emphasis to projects for children and adolescents, contemporary music, learning, historical performance practice and chamber music. The latter is carried out partially through a cooperation with The Trondheim Soloists (TS), by which ten of our string players perform as part of their professional duties.
