Dutch streetorgan

The theatre organ or cinema organ was designed to accompany silent movies. Like a symphonic organ, it is made to replace an orchestra. However, it includes many more gadgets, such as percussion and special effects, to provide a more complete array of options to the theatre organist. Theatre organs tend not to take nearly as much space as standard organs, relying on extension and higher wind pressures to produce a greater variety of tone and larger volume of sound from fewer pipes.
