Seeburg was an American design and manufacturing company of automated musical equipment, such as orchestrions, jukeboxes, and vending equipment. Before it began manufacturing its signature suite of jukebox products, Seeburg was considered to be one of the "big four" of the top coin-operated phonograph companies alongside AMI, Wurlitzer, and Rock-Ola. At the height of jukebox popularity, Seeburg machines were synonymous with the technology and a major quotidian brand of American teenage life. The company went out of business after being sold to Stern Electronics in 1982.

Orchestrion is a generic name for a machine that plays music and is designed to sound like an orchestra or band. Orchestrions may be operated by means of a large pinned cylinder or by a music roll and less commonly book music. The sound is usually produced by pipes, though they will be voiced differently from those found in a pipe organ, as well as percussion instruments. Many orchestrions contain a piano as well. At the Musical Museum in Brentford, examples may be seen and heard of several of the instrument types described below.
