NBC Symphony Orchestra
After the war, Shulman married the pianist Sophie Pratt Bostelmann on 17 September 1946. They had met previously while they were both students at Juilliard. Their first child, Jay, a cellist, was born in 1949, followed by his daughter Laurie, a musicologist, in 1951, his son Marc, a guitarist, in 1953, and his daughter Lisa in 1956. Shulman returned to his position at the NBC Symphony Orchestra in 1948. That same year he became a member of the American Society of Composers, Authors and Publishers. The following year the NBC Symphony Orchestra premiered his "Waltzes for Orchestra" under conductor Milton Katims at Carnegie Hall. In 1950 his string quartet "Threnody", written in honor of Israel's fallen soldiers, was premiered by the NBC String Quartet during Jewish Music Week. In 1954 the NBC Symphony Orchestra disbanded when Toscanini retired, and Shulman, along with several other members of the Symphony Orchestra, formed a new ensemble for NBC called the "Symphony of the Air". He remained with the Symphony of the Air for three years.
