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.

Wood and metal pipes of a variety of sizes are shown in this photograph. An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air (commonly referred to as wind) is driven through it. Each pipe is tuned to a note of the musical scale.

An organ stop is a component of a pipe organ that admits pressurized air (known as wind) to a set of organ pipes. Its name comes from the fact that stops can be used selectively by the organist; each can be "on" (admitting the passage of air to certain pipes), or "off" ( stopping the passage of air to certain pipes).
Instead of sliders, each stop knob operates a stop lever bar which runs alongside each rank of pipes. The bars sit on top of a second set of pallets and springs, one pallet per pipe per rank, called groove valves. When a stop knob is pulled, the bar moves down, opening the groove valves and admitting wind to the pipes of that rank.
