A reed pipe comprises a metal tongue (the reed) which rests against a shallot, in which is carved a tunnel. The reed and shallot are held in place by a wooden wedge. This assembly protrudes from the underside of the block and hangs down into the boot. A tuning wire is inserted through the boot and is bent to hold the reed against the shallot.
A hand-pumped Indian harmonium, of the type used in South Asia, here used at a European jazz festival.. The pump organ or reed organ is a type of organ using free-reeds that generates sound as air flows past the free-reeds, the vibrating pieces of thin metal in a frame.
The Grand Ophicleide in the Boardwalk Hall Organ, Atlantic City, New Jersey, is recognized as the loudest organ stop in the world, voiced on 100" wind pressure (0.25 bar). [1] Its tone is described by Guinness World Records as having "a pure trumpet note of ear-splitting volume, more than six times the volume of the loudest locomotive whistle."
For six generations since its founding in 1873, Schantz Organ Co. has worked on pipe and reed organs for churches across the globe.
Although these organ reeds were originally designed and manufactured for American style suction organs they became the favored reeds for their tone quality and tuning stability in Indian hand pumped harmoniums which work on an air pressure system. In order for them to be attached to the Indian harmonium reed board (as opposed to sliding into ...
The Orthotonophonium is a free reed aerophone similar to a Harmonium with 72 (sometimes 53) keys per octave, that can be played all diatonic key intervals and chords using just intonation. The instrument was created in 1914 by German physicist Arthur von Oettingen to advance his theories of harmonic dualism (now knows as Riemannian theory) .
Drawings of the reeds of regals and other reed pipes, as well as of the instrument itself, are given by Praetorius (pl. iv., xxxviii.). The regal may be seen as the ancestor of the harmonium, the reed organ, and the various varieties of "squeezebox" such as the accordion, the concertina, and the Bandoneón.
Reed organs and harmoniums of the late 19th and early 20th centuries often had a similar mechanism to a crescendo pedal. Since the player's feet were needed to pedal the bellows that provided the wind for the instrument, the mechanism was operated by a 'paddle' lever moved by one of the player's knees (the paddle being located under the keyboard).
