The Proper organ
An organ consists of a large number of pipes, each with a single tone, through which air is blown.
Since the invention, the stops are controlled via keys with rods. The stops send the air to some pipes. (The organ then is called mechanical pneumatic.) For sure such a large organ is heavy to play on.
In the late 19th century the purely pneumatic organ was developed. In this organ, the compounds are established by air pressure.
