A calliope is a North American musical instrument that produces sound by sending a gas, originally steam or, more recently, compressed air, through large whistles—originally locomotive whistles.
A drum machine is an electronic musical instrument that creates percussion sounds, drum beats, and patterns. Drum machines may imitate drum kits or other percussion instruments, or produce unique sounds, such as synthesized electronic tones. A drum machine often has pre-programmed beats and patterns for popular genres and styles, such as pop music, rock music, and dance music. Most modern drum machines made in the 2010s and 2020s also allow users to program their own rhythms and beats. Drum machines may create sounds using analog synthesis or play prerecorded samples.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones. The organs have usually two or three, up to five, manuals for playing with the hands and a pedalboard for playing with the feet. With the use of registers, several groups of pipes can be connected to one manual.
Book music is a medium for storing the music played on mechanical organs, mainly of European manufacture. Book music is made from thick cardboard, containing perforated holes specifying the musical notes to be played, with the book folded zig-zag style. Unlike the heavy pinned barrels, which could only contain a few tunes of fixed length, that had been used on earlier instruments, book music enabled large repertoires to be built up. The length of each tune was no longer determined by the physical dimensions of the instrument.
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments:
A barrel organ is a French mechanical musical instrument consisting of bellows and one or more ranks of pipes housed in a case, usually of wood, and often highly decorated. The basic principle is the same as a traditional pipe organ, but rather than being played by an organist, the barrel organ is activated either by a person turning a crank, or by clockwork driven by weights or springs. The pieces of music are encoded onto wooden barrels, which are analogous to the keyboard of the traditional pipe organ. A person who plays a barrel organ is known as an organ grinder.
The Rudolph Wurlitzer Company, usually referred to as simply Wurlitzer, is an American company started in Cincinnati in 1853 by German immigrant (Franz) Rudolph Wurlitzer. The company initially imported stringed, woodwind and brass instruments from Germany for resale in the United States. Wurlitzer enjoyed initial success, largely due to defense contracts to provide musical instruments to the U.S. military. In 1880, the company began manufacturing pianos and eventually relocated to North Tonawanda, New York. It quickly expanded to make band organs, orchestrions, player pianos and pipe or theatre organs popular in theatres during the days of silent movies.
Laurens Hammond was an American engineer and inventor. His inventions include the Hammond organ, the Hammond clock, and the world's first polyphonic musical synthesizer, the Novachord.
Orchestrion is a generic name for a machine that plays music and is designed to sound like an orchestra or band. Orchestrions may be operated by means of a large pinned cylinder or by a music roll and less commonly book music. The sound is usually produced by pipes, though they will be voiced differently from those found in a pipe organ, as well as percussion instruments. Many orchestrions contain a piano as well. At the Musical Museum in Brentford, examples may be seen and heard of several of the instrument types described below.
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. Specific types of pump organs include the harmonium using pressure system, suction reed organ using vacuum system, and the Indian harmonium; the historical types include the Kunstharmonium and the American reed organ; the earliest types include the physharmonica and the seraphine. The idea for the free reed was derived from the Chinese sheng through Russia after 1750, and the first Western free-reed instrument was made in 1780 in Denmark.
M. Welte & Sons, Freiburg and New York was a manufacturer of orchestrions, organs and reproducing pianos, established in Vöhrenbach by Michael Welte (1807–1880) in 1832.
A fairground organ is a musical organ covering the wind and percussive sections of an orchestra. Originated in Paris, France, it was designed for use in commercial fairground settings to provide loud music to accompany rides and attractions, mostly merry-go-rounds. Unlike organs for indoor use, they are designed to produce a large volume of sound to be heard above the noises of crowds and fairground machinery.
Museum Speelklok is a museum in Utrecht, Netherlands, specializing in self-playing musical instruments. Since 1984, it has been housed in the centre of Utrecht in a former church called Buurkerk. Among the instruments on display are music boxes, musical clocks, pianolas, barrel organs and a turret clock with a carillon, most of which are still able to play for visitors. The word speelklok means musical clock.
DeBence Antique Music World is a museum in Franklin, Pennsylvania whose collection contains more than 100 antique mechanical musical instruments, including music boxes, band organs, player pianos, a nickelodeon piano, as well as a number of other antiques. Many of the collection's mechanical instruments are rare; a number are among only a few manufactured, and a few are among the last in existence. Although the collection's value cannot be measured, an offer for a sum of multiple millions of dollars was once rejected.
Gavioli & Cie were a Franco–Italian organ builder company that manufactured fairground organs in both Italy and later France.
The Aeolian Company was a musical-instrument making firm whose products included player organs, pianos, sheet music, records and phonographs. Founded in 1887, it was at one point the world's largest such firm. During the mid 20th century, it surpassed Kimball to become the largest supplier of pianos in the United States, having contracts with Steinway & Sons to provide its Duo-Art system for installation in Steinway pianos. It went out of business in 1985.
Gulbransen Company was a musical instrument manufacturer of player pianos and home organs in the United States. It also made reed organs. It was originally established in 1904 by Axel Gulbransen as Gulbransen Piano Company.
John McTammany was a Scottish-born American inventor who is credited with a number of patents. He immigrated to the United States as a teenager and served in the American Civil War.
Edwin Scott Votey was an American businessman, inventor, industrial designer, and manufacturer of pianos and organs. He worked in the organ field all his adult life and had over twenty patents. He invented or co-invented several inventions for World War I. One was a pilotless airplane that was going to be used to drop bombs on the enemy but was never used.
Henry Bishop Horton was an American inventor, remembered chiefly for his inventions in automatic music players and clock-making.
