TONO is owned and managed by songwriters, composers, lyricists and music publishers. TONO is led by a board elected by the annual meeting, which is TONO's highest body.

TONO's voting members have the right to vote at the annual meeting and are eligible for election to positions of trust. The board members are elected for different periods in an overlapping arrangement. The purpose is to create continuity in the board's work. TONO's board members are elected for 1 and 2 years respectively. The employee-elected representatives are elected by the employees in TONO's administration.

TONO's board consists of individual, personally responsible board members. The board consists of two board members who are members of NOPA, two who are members of the Norwegian Composers' Association, two who are independent, two who are members of Musikkforleggerne and three who are elected by and among the employees. Below is TONO's board for 2026/2027. The photos were taken by Bård Gudim, except for the photos of Tom Hugo Hermansen and Asbjørn Myhrvold, which were taken by Agnete Brun.
