Sør-Trøndelag Orkesterforening

Sør-Trøndelag Orkesterforening, which performs as Midtnorsk Symfoniorkester, is an amateur symphony orchestra in Trondheim. Founded in 2003 through a merger of Trondheim Byorkester and Midt-Trøndelag Symfoniorkester, it has about 60 musicians and a full symphonic line-up. It plays varied classical repertoire, from symphonies and soloist concerts to choral works and musicals, with six to eight concerts a year in Trondheim and elsewhere in Trøndelag, including a 17 May concert in Vår Frue kirke and its Young Soloists series.
