The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert [1] and first manufactured in 1935. [2] Various models were produced, which originally used tonewheels to generate sound via additive synthesis , where component waveform ratios are mixed by sliding switches called drawbars and imitate the pipe organ's registers.
In 1938, the FTC ordered Hammond to "cease and desist" a number of advertising claims, including that its instrument was equivalent to a $10,000 pipe organ. After the FTC's decision, Hammond claimed that the hearings had vindicated his company's assertions that the organ produced "real", "fine", and "beautiful" music, phrases which were each ...
The pipe organ is a musical instrument that produces sound by driving pressurised air (called wind) through the organ pipes selected from a keyboard.Because each pipe produces a single pitch, the pipes are provided in sets called ranks, each of which has a common timbre, volume, and construction throughout the keyboard compass.
The organ is electrically powered, replacing the reed organ's twin bellows pedals with a single swell (or "expression") pedal more like that of a pipe organ. Instead of having to pump at a constant rate, as had been the case with the reed organ, the organist simply varies the position of this pedal to change the volume as desired.

An 8 ′ stop is said to sound at "unison pitch": the keys on the organ console produce the expected pitch (e.g. the key for middle C causes a middle C pipe to speak), like a piano. In a rank of stopped pipes, the lowest pipe is 4 feet in length but sounds at unison pitch—that is, at the same pitch as an 8 ′ open pipe—so it is known as an ...
