See also: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
- METAL (through Fr. from Lat. metallum, mine, quarry, adapted from Gr. µATaXAov, in the same sense, probably connected with ,ueraAAdv, to search after, explore, µeTa, after, aAAos, other)
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
