The theatre organ is an instrument which works in the same way as a pipe organ, the difference being that the pipes in a theatre organ are made to sound like instruments in an orchestra.
The organ is played from a "horseshoe" shaped console.

These organs were developed between around 1910 till around 1920`s. They were installed in movie palaces to provide music at a cheaper cost than the orchestra.
There sound is very effective.
