Accordions are a family of box-shaped musical instruments of the bellows-driven free reed aerophone type. The essential characteristic of the accordion is to combine in one instrument a melody section, also called the diskant, usually on the right-hand keyboard, with an accompaniment or Basso continuo functionality on the left-hand. The musician normally plays the melody on buttons or keys on the right-hand side, and the accompaniment on bass or pre-set chord buttons on the left-hand side. A person who plays the accordion is called an accordionist.
The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock. The many types of harmonica include diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth to direct air into or out of one holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. The most common is the diatonic Richter-tuned with ten air passages and twenty reeds, often called the blues harp. A harmonica reed is a flat, elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound.
A pan flute is a musical instrument based on the principle of the closed tube, consisting of multiple pipes of gradually increasing length. Multiple varieties of pan flutes have been popular as folk instruments. The pipes are typically made from bamboo, giant cane, or local reeds. Other materials include wood, plastic, metal, and clay.
The melodica is a handheld free-reed instrument similar to a pump organ or harmonica. It features a musical keyboard on top, and is played by blowing air through a mouthpiece that fits into a hole in the side of the instrument. The keyboard usually covers two or three octaves. Melodicas are small, lightweight, and portable, and many are designed for children to play. They are popular in music education programs, especially in Asia. The modern form of the instrument was invented by Hohner in the late 1950s, though similar instruments have been known in Italy since the 19th century.
The uilleann pipes, also known as Union pipes and sometimes called Irish pipes, are the characteristic national bagpipe of Ireland. Their current name is a partial translation of the Irish language terms píobaí uilleann, from their method of inflation. There is no historical record of the name or use of the term uilleann pipes before the 20th century. It was an invention of Grattan Flood and the name stuck. People mistook the term 'union' to refer to the 1800 Act of Union; however, this is incorrect as Breandán Breathnach points out that a poem published in 1796 uses the term 'union'.
The sheng is a Chinese mouth-blown polyphonic free reed instrument consisting of vertical pipes.
A free reed aerophone is a musical instrument that produces sound as air flows past a vibrating reed in a frame. Air pressure is typically generated by breath or with a bellows. In the Hornbostel–Sachs system, it is number: 412.13. Free reed instruments are contrasted with non-free or enclosed reed instruments, where the timbre is fully or partially dependent on the shape of the instrument body, Hornbostel–Sachs number: 42.
A key is a component of a musical instrument, the purpose and function of which depends on the instrument. However, the term is most often used in the context of keyboard instruments, in which case it refers to the exterior part of the instrument that the player physically interacts in the process of sound production.
Hohner Musikinstrumente GmbH & Co. KG is a German manufacturer of musical instruments, founded in 1857 by Matthias Hohner (1833–1902). It is a subsidiary of Matth. Hohner AG. The roots of the Hohner firm are in Trossingen, Baden-Württemberg. Hohner has manufactured a wide range of instruments, such as harmonicas, kazoos, accordions, recorder flutes, melodicas, banjos, electric, acoustic, resonator and classical guitars, basses, mandolins and ukuleles. Hohner is known mostly for its harmonicas.
A flue pipe is an organ pipe that produces sound through the vibration of air molecules, in the same manner as a recorder or a whistle, in a pipe organ. Air under pressure is driven through a flue and against a sharp lip called a labium, causing the column of air in the pipe to resonate at a frequency determined by the pipe length. Thus, there are no moving parts in a flue pipe. This is in contrast to reed pipes, whose sound is driven by beating reeds, as in a clarinet.
A button accordion is a type of accordion on which the melody-side keyboard consists of a series of buttons. This differs from the piano accordion, which has piano-style keys. Erich von Hornbostel and Curt Sachs categorize it as a free reed aerophone in their classification of instruments, published in 1914. The sound from the instrument is produced by the vibration of air in reeds. Button accordions of various types are particularly common in European countries and countries where European people settled. The button accordion is often confused with the concertina; the button accordion's buttons are on the front of the instrument, where as the concertina's are on the sides and pushed in parallel with the bellows.
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.
A melodeon or diatonic button accordion is a member of the free-reed aerophone family of musical instruments. It is a type of button accordion on which the melody-side keyboard contains one or more rows of buttons, with each row producing the notes of a single diatonic scale. The buttons on the bass-side keyboard are most commonly arranged in pairs, with one button of a pair sounding the fundamental of a chord and the other the corresponding major triad.
A reed pipe is an organ pipe that is sounded by a vibrating brass strip known as a reed. Air under pressure is directed towards the reed, which vibrates at a specific pitch. This is in contrast to flue pipes, which contain no moving parts and produce sound solely through the vibration of air molecules. Reed pipes are common components of pipe organs.
A Cajun accordion, also known as a squeezebox, is single-row diatonic button accordion used for playing Cajun and Creole music.
The couesnophone, also known as the goofus or queenophone, is a free-reed musical instrument in a saxophone shape, patented by French instrument manufacturer Couesnon in 1924. Its reeds vibrate when the desired keys are activated and the player blows through a tube. "Best described as a mouth-blown accordion," "it sounded like a cross between a harmonica and an accordion."
A reed rank inside an accordion is a single full set of the reeds that are the means to achieve the instrument's sound range. These reed ranks are located in the reed chamber. Most accordions to this date typically have between two and four reed ranks on the treble side and between three and five reed ranks on the bass side. These can usually be selected individually or combined in various ways to provide a range of different timbres, by use of register switches arranged by register from high to low. More of the top-line expensive accordions may contain five or six reed blocks on the treble side for different tunings, typically found in accordions that stress musette sounds.
A digital accordion is an electronic musical instrument that uses the control features of a traditional accordion to trigger a digital sound module that produces synthesized or digitally sampled accordion sounds or, in most instruments, a range of non-accordion sounds, such as orchestral instruments, pipe organ, piano, guitar, and so on. Digital accordions typically encode and transmit key presses and other input as Musical Instrument Digital Interface (MIDI) messages. Most digital accordions need to be plugged into a keyboard amplifier or PA system to hear their sounds.
