A keyboard instrument is a musical instrument played using a keyboard, a row of levers which are pressed by the fingers. The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings.
A player piano is a self-playing piano, containing a pneumatic or electro-mechanical mechanism that operates the piano action via programmed music recorded on perforated paper, or in rare instances, metallic rolls, with more modern implementations using MIDI. The rise of the player piano grew with the rise of the mass-produced piano for the home in the late 19th and early 20th century. Sales peaked in 1924, then declined as the improvement in phonograph recordings due to electrical recording methods developed in the mid-1920s. The advent of electrical amplification in home music reproduction via radio in the same period helped cause their eventual decline in popularity, and the stock market crash of 1929 virtually wiped out production.
The pipe organ is a musical instrument that produces sound by driving pressurized air 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 and volume throughout the keyboard compass. Most organs have many ranks of pipes of differing timbre, pitch, and volume that the player can employ singly or in combination through the use of controls called stops.
In music, the organ is a keyboard instrument of one or more pipe divisions or other means for producing tones, each played with its own keyboard, played either with the hands on a keyboard or with the feet using pedals.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument, an electronic or digital derivative of keyboard instruments. Broadly speaking, the term electronic keyboard or just a keyboard can refer to any type of digital or electronic keyboard instrument. These include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. However, an electronic keyboard is more specifically a synthesizer with a built-in low-wattage power amplifier and small loudspeakers.
A piano roll is a music storage medium used to operate a player piano, piano player or reproducing piano. Piano rolls, like other music rolls, are continuous rolls of paper with perforations (holes) punched into them. The perforations represent note control data. The roll moves over a reading system known as a 'tracker bar' and the playing cycle for each musical note is triggered when a perforation crosses the bar and is read.
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 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 which 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.
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.
An expression pedal is an important control found on many musical instruments including organs, electronic keyboards and pedal steel guitar. The musician uses the pedal to control different aspects of the sound, commonly volume. Separate expression pedals can often be added to a guitar amplifier or effects unit and used to control many different aspects of the tone.
A fairground organ is a pneumatic musical organ covering the wind and percussive sections of an orchestra. Designed for use in a commercial public fairground setting to provide loud music to accompany fairground rides and attractions, mostly used on merry-go-rounds. Unlike organs intended for indoor use, they are designed to produce a large volume of sound to be heard over and above the noise of crowds of people and fairground machinery.
A street organ played by an organ grinder is an automatic mechanical pneumatic organ designed to be mobile enough to play its music in the street. The two most commonly seen types are the smaller German and the larger Dutch street organ.
A music roll is a storage medium used to operate a mechanical musical instrument. They are used for the player piano, mechanical organ, electronic carillon and various types of orchestrion. The vast majority of music rolls are made of paper. Other materials that have been utilized include thin card (Imhof-system), thin sheet brass (Telektra-system), composite multi-layered electro-conductive aluminium and paper roll (Triste-system) and, in the modern era, thin plastic or PET film.
A dance organ is a mechanical organ designed to be used in a dance hall or ballroom. Being intended for use indoors, dance organs tend to be quieter than the similar fairground organ.
Gavioli & Cie were a Franco–Italian organ builder company that manufactured fairground organs in both Italy and later France.
The North Tonawanda Barrel Organ Factory was a street organ manufacturing company and building, located in North Tonawanda, New York. Started by expatriate German Eugene de Kleist with backing from Allan Herschell, the company was later purchased by the Wurlitzer company.
Music technology is the study or the use of any device, mechanism, machine or tool by a musician or composer to make or perform music; to compose, notate, play back or record songs or pieces; or to analyze or edit music.
Mechanical music technology is the use of any device, mechanism, machine or tool by a musician or composer to make or perform music; to compose, notate, play back or record songs or pieces; or to analyze or edit music. The earliest known applications of technology to music was prehistoric peoples' use of a tool to hand-drill holes in bones to make simple flutes. Ancient Egyptians developed stringed instruments, such as harps, lyres and lutes, which required making thin strings and some type of peg system for adjusting the pitch of the strings. Ancient Egyptians also used wind instruments such as double clarinets and percussion instruments such as cymbals. In Ancient Greece, instruments included the double-reed aulos and the lyre. Numerous instruments are referred to in the Bible, including the horn, pipe, lyre, harp, and bagpipe. During Biblical times, the cornet, flute, horn, organ, pipe, and trumpet were also used. During the Middle Ages, hand-written music notation was developed to write down the notes of religious Plainchant melodies; this notation enabled the Catholic church to disseminate the same chant melodies across its entire empire.
