Pump organ
The pump organ or reed organ is a type of musical instrument that creates sound using free reeds. These reeds are thin metal strips that vibrate when air moves over them inside a frame. Different types include the pressure-based harmonium, the suction reed organ (which uses a vacuum system), and the Indian harmonium.
Electric organ
An electric organ, also called an electronic organ, is a keyboard instrument that came from the harmonium, pipe organ, and theatre organ. It was first made to copy the sounds of these instruments or the sounds of an orchestra. Over time, it has now become many different kinds of instruments.
Theatre organ
A theatre organ, also called a theater organ or cinema organ in the United Kingdom, is a type of pipe organ created to play music for silent films between the 1900s and the 1920s. Theatre organs have curved rows of stop tabs, which are small, tongue-shaped switches, placed above and around the keyboards on their consoles. These consoles often had bright-colored stop tabs and built-in lights.
Pipe organ
The pipe organ is a musical instrument that makes sound by sending air (called wind) through pipes chosen by pressing keys on a keyboard. Each pipe creates one note and one pitch, so pipes are grouped into sets called ranks. All pipes in a rank have the same sound quality, loudness, and design, but they produce different pitches.
Hammond organ
The Hammond organ is an electric instrument created by Laurens Hammond and John M. Hanert. It was first made in 1935.
Telharmonium
The Telharmonium, also called the Dynamophone, was an early electrical organ created by Thaddeus Cahill around 1896. It received a patent in 1897. Electrical signals from the Telharmonium were sent through wires and heard at the receiving end using “horn” speakers.

Ondes Martenot
The ondes Martenot (pronounced OHND mar-tuh-NOH; French: [ɔ̃d maʁtəno], meaning “Martenot waves”) or ondes musicales (“musical waves”) is an early electronic musical instrument. Early versions were played by moving a ring attached to a wire, making sounds that wavered like those from a theremin. Later, a keyboard with a special vibrato feature was added.
