The piece of metal is called a reed. The pump organ is a type of free-reed organ that generates sound as air flows past a vibrating piece of thin metal in a frame.

The organ case is solid oak. 1939, but Estey built similar models up through the 1950s. An expert dates the organ to c. It was manufactured by the Estey Organ Company of Brattleboro, Vermont. The idea for the free reed was imported from China through Russia after 1750, and the first Western free-reed instrument was made in 1780 in Denmark.
The portable, hand-pumped harmonium or samvadini is a major instrument on the Indian Subcontinent developed by Indians to meet local needs. During this time Estey Organ and Mason & Hamlin were popular manufacturers.Alongside the furniture-sized instruments of the west, smaller designs exist. Several million free-reed organs and melodeons were made in the US and Canada between the 1850s and the 1920s, some which were exported. The finer pump organs had a wider range of tones, and the cabinets of those intended for churches and affluent homes were often excellent pieces of furniture. They generally had one or sometimes two manuals, with pedal-boards being rare.
The harmonium's design incorporates free reeds and derives from the earlier regal. According to Curt Sachs, Kratzenstein suggested that the instrument be made, but that the first organ with free reeds was made by Abbé Georg Joseph Vogler in Darmstadt. Christian Gottlieb Kratzenstein (1723–1795), professor of physiology at Copenhagen, was credited with the first free-reed instrument made in the Western world, after winning the annual prize in 1780 from the Imperial Academy of St. The instrument's free-reed was unknown in Europe at the time, and the concept quickly spread from Russia across Europe. That instrument received attention, due to its use by Johann Wilde.
A mechanic who had worked in the factory of Alexandre in Paris emigrated to the United States and conceived the idea of a suction bellows, instead of the ordinary bellows that forced the air outward through the reeds. There was concurrent development of similar instruments. Alexandre Debain improved Grenié's instrument and gave it the name harmonium when he patented his version in 1840. He called it an orgue expressif (expressive organ), because his instrument was capable of greater expression, as well as of producing a crescendo and diminuendo.
Harmoniums reached the height of their popularity in the West in the late 19th and early 20th centuries. The word became a common designation of that type of resort that offered entertainment to men. The term melodeon was applied to concert saloons in the Victorian American West because of the use of the reed instrument.
This "export" market was sufficiently lucrative for manufacturers to produce harmoniums with cases impregnated with chemicals to prevent woodworm and other damaging organisms found in the tropics. An added attraction of the harmonium in tropical regions was that the instrument held its tune regardless of heat and humidity, unlike the piano. Harmoniums generally weigh less than similar sized pianos and are not easily damaged in transport, thus they were also popular throughout the colonies of the European powers in this period not only because it was easier to ship the instrument out to where it was needed, but it was also easier to transport overland in areas where good-quality roads and railways may have been non-existent.
Some were even built with pedal keyboards, which required the use of an assistant to run the bellows or, for some of the later models, an electrical pump. Small numbers of harmoniums were built with two manuals (keyboards). Expensive harmoniums were often built to resemble pipe organs, with ranks of fake pipes attached to the top of the instrument. These ranged from simple models with plain cases and only four or five stops (if any at all), up to large instruments with ornate cases, up to a dozen stops and other mechanisms such as couplers.
The Hammond organ could imitate the tonal quality and range of a pipe organ whilst retaining the compact dimensions and cost-effectiveness of the harmonium as well as reducing maintenance needs and allowing a greater number of stops and other features. The invention of the electronic organ in the mid-1930s spelled the end of the harmonium's success in the West, although its popularity as a household instrument had already declined in the 1920s as musical tastes changed. For missionaries, chaplains in the armed forces, travelling evangelist etc., reed organs that folded up into a container the size of a very large suitcase or small trunk were made these had a short keyboard and few stops, but they were more than adequate for keeping hymn singers more or less on pitch.
Therefore, they are essentially identical for the Western and Indian harmoniums and the reed organ. Modern electronic keyboards can emulate the sound of the pump organ.Two reeds from a Mason & Hamlin reed organ.The acoustical effects described below are a result of the free-reed mechanism. The majority of Western harmoniums today are in the hands of enthusiasts, though the instrument still remains popular in South Asia. It was not uncommon for harmoniums to be "modernised" by having electric blowers fitted, often very unsympathetically. As the existing stock of instruments aged and spare parts became hard to find, more and more were either scrapped or sold. It was common for manufacturers to patent the action mechanism used on their instruments, thus requiring any new manufacturer to develop their own version as the number of manufacturers grew, this led to some instruments having hugely complex arrays of levers, cranks, rods and shafts, which made replacement with an electronic instrument even more attractive.The last mass-producer of harmoniums in North America was the Estey company, which ceased manufacture in the mid-1950s a couple of Italian companies continued into the 1970s.
Additional modified or novel instruments were used for experimental and educational purposes notably, Bosanquet's Generalized keyboard was constructed in 1873 for use with a 53-tone scale. This arrangement was difficult to play on. He subdivided the octave to 28 tones, to be able to perform modulations of 12 minor and 17 major keys in just intonation without going into harsh dissonance that is present with the standard octave division in this tuning. And as its vibrators also admit of a delicate and durable tuning, it appeared to me peculiarly suitable for experiments on a more perfect system of tones." Using two manuals and two differently tuned stop sets, he was able to simultaneously compare Pythagorean to just and to equal-tempered tunings and observe the degrees of inharmonicity inherent to the different temperaments.
However, Rayleigh acknowledged that maintaining constant pressure in the bellows is difficult and fluctuation of the pitch occurs rather frequently as a result. The harmonium had the advantage of providing clear overtones that enabled the reliable counting of beats by two listeners, one per note. Lord Rayleigh also used the harmonium to devise a method for indirectly measuring frequency accurately, using approximated known equal temperament intervals and their overtone beats. Another famous reed organ that was evaluated was built by Poole.
