Iran's first symphony orchestra, the Tehran Symphony Orchestra, was founded by Qolam-Hoseyn Minbashian in 1933. It was reformed by Parviz Mahmoud in 1946, and is currently Iran's oldest and largest symphony orchestra. Later, by the late 1940s, Ruhollah Khaleqi founded the country's first national music society, and established the School of National Music in 1949.
