SiTron

SiTron (Sinfonietta in Trondheim) is a chamber ensemble specializing in contemporary music. Its musicians are drawn from Trondheim’s professional music scene, and the ensemble serves as a creative meeting place for performers from the Trondheim Symphony Orchestra, the Royal Norwegian Air Force Band, NTNU, and the city’s vibrant freelance community.

SiTron performs contemporary works with a focus on notated music from 1920 to the present day, as well as music that incorporates elements of improvisation. Each year, SiTron commissions and premieres several new works, contributing significantly to the development of new repertoire. Through this work, both emerging and established composers — regional, national, and international — are given new opportunities and platforms to present their music.
