radio orchestra

A radio orchestra (or broadcast orchestra) is an  orchestra employed by a radio network (and sometimes television networks) in order to provide programming as well as sometimes perform incidental or theme music for various shows on the network. In the heyday of radio such orchestras were numerous, performing classical, popular, light music and jazz. However, in recent decades, broadcast orchestras have become increasingly rare. Those that still exist perform mainly classical and contemporary orchestral music, though broadcast light music orchestras, jazz orchestras and big bands are still employed by some radio stations in Europe.
