Image:Accordion.pngAn accordion is a musical instrument of the handheld bellows-driven free reed aerophone family, sometimes referred to as squeezeboxes.
The accordion is played by compression and expansion of a bellows, which generates air flow across reeds; a keyboard controls which reeds receive air flow and therefore the tones produced.

Physical description
Modern accordions consists of a body in two parts, each generally rectangular in shape, separated by a bellows. On each part of the body is a keyboard containing buttons, levers or piano-style keys. When pressed, the buttons travel in a direction perpendicular to the motion of the bellows (towards the performer). Most, but not all modern accordions also have buttons capable of producing entire chords, whereas concertinas' buttons produce only single notes.
The related concertina differs in that its buttons never produce chords and travel parallel to the travel of the bellows (towards the opposite end of the instrument); there are also differences in the internal materials, construction, mechanics, and tone color, but the basic principles of sound production are identical.
History
The accordion is one of several European inventions of the early 19th century that used free reeds driven by a bellows; notable among them were:
- The Aeoline, by German Bernhard Eschenbach (and his cousin, Caspar Schlimbach), 1810.
- Was a piano with added aeoline register.
- Aeoline Harmonika and Pysharmonika are very similar names at that time.
- Aeoline and Aura ware first without bellows or keyboard.
- The Hand Physhamonika Anton Haeckel 1818 Hand type mentioned in music newspaper 1821.
- The flutina, by Pichenot Jeune, ca. 1831
- The concertina, patented in two forms (perhaps independently):
- Carl Friedrich Uhlig, 1834.
- Sir Charles Wheatstone, examples built after 1829, but not patented until 1844
An instrument called accordion was first patented in 1829 by Cyrill Demian in Vienna. (Interestingly, the original patent shows the name "eoline" crossed out and replaced with "accordion" in different handwriting). Demian's instrument bore little resemblance to modern instruments: It only had a left hand keyboard; the right hand simply operated the bellows. One key feature for which Damian sought the patent was the sounding of an entire chord by depressing one key. His instrument also could sound two different chords with the same key: one for each bellows direction (press, draw); this is called a bisonoric action. If we read the text of the patent carefully and take into account that at that time in Vienna mouth harmonicas with "Kanzellen" (chambers) had already been sold for many years and also the bigger hand bellows driven instrument had been sold for some years, we can see why he could not get a patent for a aeoline, because it was already there. He could not get a patent for the diatonic arranging of keys the system ware in use on mouth blown instruments. So he thought it a good idea to get a patent for an accompanying instrument: an accordion played with the left hand, also opposite to the way the chromatic hand harmonica ware played at that time. And he mentions that because it is so small and light weight it must be a good instrument to take along on journeys and accompany oneself when singing. Demian also mentions that the instrument my be combined with a treble side as well, but he thinks it is better to stay with the bass side on its own to keep the cost and the weight down. Still, his patent included the doubled version. By 1833 we find a great variety of instruments mentioned in the writing of the musician Adolph Müller "Schule für Accordion". There is also evidence that Whetstone did know this types of instrument at that time.
So he could think of putting his idea of arranging the keys into reality by having a variety of reed instruments to test. One should also not forget, that at that time Vienna and London had a very close relationship, especially if we think about the musicians performing in Vienna and London very often in the same year.
Jeune's flutina resembles Wheatstone's concertina in internal construction and tone color, but it appears to complement Demian's accordion functionally. The flutina is a one-sided bisonoric melody-only instrument whose keys are operated with the right hand while the bellows is operated with the left. When the two instruments are combined, the result is quite similar to diatonic button accordions still manufactured today.
Further innovations followed and continue to the present: Various keyboard systems have been developed; voicings (the combination of multiple tones at different octaves) have been developed, with mechanisms to switch between different voices during performance; different methods of internal construction to improve tone, stability and durability, and so on.
Piano accordions
Image:KlavierAccordeon.jpg The piano accordion is the instrument most often indicated by the term "accordion", but it is one of the most recent inventions among accordion types, appearing late in the 19th century and not accepted worldwide until the early 20th century. It has a right-hand keyboard similar to a piano; this facilitates learning for musicians already familiar or proficient on the piano.
The left hand keyboard is usually configured in the Stradella system, a combination of chords and single notes, arranged in a uniform series by harmonic relationship. Occasionally a free bass left hand is used, which has a series of single buttons in an arrangement similar to the chromatic button accordion. The free bass system facilitates the playing of bass melodies.
Converter bass systems allow an instrument to be readily converted from a Stradella system to a free-bass system with a switch.
The instrument was popularized in the United States by Count Guido Deiro who was the first piano accordionist to perform in Vaudeville. He is credited with making the first recordings of the instrument in 1908, making the first radio broadcast of the accordion in 1921 and the first sound motion picture featuring the accordion, for Vitaphone, in 1928.
Button accordions
On button accordions the melody-side keyboard consists of a series of buttons (rather than piano-style keys.) There exists a wide variation in keyboard systems, tuning, action and construction of these instruments.
Diatonic button accordions have a melody-side keyboard that is limited to the notes of diatonic scales in a small number of keys (sometimes only one). The bass side usually contains the principal chords of the instrument's key and the root notes of those chords.
Image:Busking Accordionist.jpgAlmost all diatonic button accordions (e.g.: melodeon) are bisonoric, meaning each button produces two notes: one when the bellows is compressed, another while it is expanded; a few instruments (e.g.: garmon') are unisonoric, with each button producing the same note regardless of bellows direction; still others have a combination of the two types of action: See Hybrids below.
A chromatic button accordion is a type of button accordion where the melody-side keyboard consists of uniform rows of buttons arranged so that the pitch increases chromatically along diagonals. The bass-side keyboard is usually the Stradella system, one of the various free-bass systems, or a converter system. Included among chromatic button accordions is the Russian bayan. Sometimes an instrument of this class is simply called a chromatic accordion, although other types, including the piano accordion, are fully chromatic as well. Chromatic button accordions are preferred by many classical music performers, since the treble keyboard is more dense than that of a piano accordion, allowing a much greater range.
Various cultures have made their own versions of the accordion, adapted to suit their own music. Russia alone has several, including the Bayan, Garmon, Livenka, and Saratovskaya Garmonika.
Various hybrids have been created between instruments of different keyboards and actions. Many remain curiosities, only a few have remained in use. Some notable examples are:
- The Schrammel accordion, used in Viennese chamber music and Klezmer, which has the treble keyboard of a chromatic button accordion and a bisonoric bass keyboard, similar to an expanded diatonic button accordion.
- The schwyzerörgeli or Swiss organ, which has a (usually) 3-row diatonic treble and 18 unisonoric bass buttons in a bass/chord arrangement (actually a subset of the Stradella system), that travel parallel to the bellows motion.
- The trikitixa of the Basque people has a 2-row diatonic, bisonoric treble and a 12-button diatonic unisonoric bass.
- In Scotland, the favoured diatonic accordion is, paradoxically, the instrument known as the British Chromatic Accordion. While the right hand is bisonoric, the left hand follows the Stradella system. The elite form of this instrument is generally considered to be the German manufactured "Shand Morino", produced by Hohner with the input of the late Sir Jimmy Shand. [1]
Stradella bass system
Image:Acchords.pngThe Stradella Bass System uses rows of buttons arranged in a circle of fifths; this places the principal major chords of a key in three adjacent rows. Each row contains, in order: A major third (the "counter-bass" note), the root note, the major chord, the minor chord, the seventh chord, and the diminished seventh chord.
Depending on the price, size or origin of the instrument, some rows may be missing completely or in different positions. In most Russian layouts the diminished seventh chord row is moved by one button, so that the C diminished seventh chord is where the F diminished seventh chord would be in a standard Stradella layout; this is done in order to achieve a better reachability with the forefinger.
Common configurations are:
- "12 Bass" accordion: Fundamental Bass goes from B♭ to A (the third to eighth column in the picture above), and only has Fundamental Bass and major chords.
- "24 Bass" goes from A♭ to A, and has Fundamental Bass, major and minor chords
- "32 Bass" goes from E♭ to E, and has FB, major, minor and seventh chords
- "48 Bass" goes from E♭ to E, and has all six rows
- "72 Bass" goes from D♭ to F♯, and has all six rows
- "80 Bass" goes from C♭ to G♯, and has everything except diminished
- "96 Bass" is as 80 Bass, but with all six rows
- "120 Bass" goes from A♭♭ (i.e. low G) to A♯ — that's 20 columns — with all six rows.
Free bass systems
There are various free bass systems in use; most consist of a rotated version or mirror image of one of the melody layouts used in chromatic button accordions. One notable exception is the Titano line of convertor bass, which repeats the first two bass rows of the Stradella system one and two octaves higher moving outward from the bellows.
Skillfull use of the free bass system enabled the performance of classical piano music, rather than music arranged specifically for the accordion's standard chorded capability. Beginning in the 1960s, competitive performance on the accordion of classical piano compositions, by the great masters of music, occurred. Although never mainstreamed in the larger musical scene, this convergence with traditional classical music propelled young accordionists to an ultimate involvement with classical music heretofore not experienced.
