An organ pipe is a sound-producing element of the pipe organ that ... A large diameter pipe will favor the fundamental tone and restrict high frequency harmonics ...
Organ pipes are so sensitive to temperature that the body heat of the organ tuner can affect the tuning. If one holds a small metal flue pipe briefly in one's hand and then returns it to the chest ( windchest ), its pitch (relative to a tuning reference) can be heard to change as the pipe returns to room temperature.
An organ pipe, or a harpsichord string, designated as eight-foot pitch (8′) is sounded at standard, ordinary pitch. [1] For example, the A above middle C in eight-foot pitch would be sounded at 440 Hz (or at some similar value, depending on how concert pitch was set at the time and place the organ or harpsichord was made).
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 wider the pipe, the greater the suppression. Thus, other factors being equal, wide pipes are poor in harmonics, and narrow pipes are rich in harmonics. The scale of a pipe refers to its width compared to its length, and an organ builder will refer to a flute as a wide-scaled stop, and a string-toned gamba as a narrow-scaled stop.
A flue stop that is the "backbone" sound of the organ. Most commonly at 8 ft in manuals, and 8 ft or 16 ft in the pedals. Diaphone: Diaphonic Diapason Valvular: A special type of organ pipe that produces tone by using a felt hammer to beat air through the resonator. Common on theatre organs but not often used in classical instruments. Dulcian ...

A reed pipe (also referred to as a lingual pipe) is an organ pipe that is sounded by a vibrating brass strip known as a reed. Air under pressure (referred to as wind ) is directed towards the reed, which vibrates at a specific pitch .
