ACCORDION (Fr. accordeon; Ger. Handharmonica, Ziehharmonica)  , a small portable See also:reed See also:wind See also:instrument with See also:keyboard, the smallest representative of the See also:organ See also:family, invented in 1829 by Damian, in See also:Vienna . The See also:accordion consists of a See also:bellows of many folds, to which is attached a keyboard with from 5 to 50 keys . The keys on being depressed, while the bellows are being worked, open valves admitting the wind to See also:free reeds, consisting of narrow See also:tongues of See also:metal riveted some to the upper, some to the See also:lower See also:board of the bellows, having their free ends See also:bent, some inwards, some outwards . Each See also:key produces two notes, one from the inwardly bent reed when the bellows are compressed, the other from the outwardly bent reed by suction (as in the See also:American organ; see See also:HARMONIUM) when the bellows are See also:expanded . The See also:pitch of the See also:note is determined by the length and thickness of the reeds, reduction of the length tending to sharpen the note, while reduction of the thickness Iowers it . The right See also:hand plays the See also:melody on the keyboard, while the See also:left See also:works the bellows and manipulates the two or three See also:bass See also:harmony keys, which See also:sound the See also:simple chords of the tonic and dominant . The archetype of the accordion is the See also:cheng (q.v.), or See also:Chinese organ, between which and the harmonium it forms a connecting See also:link structurally, although not invented for some See also:thirty years after the harmonium . The timbre of the accordion is coarse and devoid of beauty, but in the hands of a skilful performer the best See also:instruments are not entirely without See also:artistic merit . Improvements in the construction of the accordion produced the See also:concertina (q.v.), melodion and melophone .
