A keyboard to be played by the hands is called a manual (from the Latin manus, "hand"); an organ with four keyboards is said to have four manuals. Most organs also have a pedalboard, a large keyboard to be played by the feet. [Note that the keyboards are never actually referred to as "keyboards", but as "manuals" and "pedalboard", as the case ...
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.

Pedalboards range in size from 13 notes on small spinet organs designed for in-home use (an octave, conventionally C 2 –C 3) to 42 notes (three and a half octaves, G 1 –C 5) on church or concert organs. Modern pipe organs typically have 30- or 32-note pedalboards, while some electronic organs and many older pipe organs have 25-note pedalboards.
Most accordions have automatic or preset switches, similar to voice selection on an electronic keyboard, or (more precisely) to a preset combination action in a pipe organ. These switches control which reed ranks are enabled (opened up) or disabled (closed off): some switches enable a single reed rank, others enable several simultaneous reed ranks.
For six generations since its founding in 1873, Schantz Organ Co. has worked on pipe and reed organs for churches across the globe.
Elaborate pipe organs and theater organs can have four or more manuals. The manuals are set into the organ console (or "keydesk"). The layout of a manual is roughly the same as a piano keyboard, with long, usually ivory or light-colored keys for the natural notes of the Western musical scale , and shorter, usually ebony or dark-colored keys for ...
Virtual pipe organs use MIDI to access samples of real pipe organs stored on a computer, as opposed to digital organs that use DSP and processor hardware inside a console to produce the sounds or deliver the sound samples. Touch screen monitors allows the user to control the virtual organ console; a traditional console and its physical stop and ...
