See also:CONCERTINA, or MELODION (Fr. concertina, Ger. Ziehharmonica or Bandoneon)
, a See also:wind See also:instrument of the seraphine See also:family with See also:free reeds, forming a See also:link in the See also:evolution of the See also:harmonium from the mouth See also:organ, intermediate links being the See also:cheng and the See also:accordion
.
The See also:concertina consists of two hexagonal or rectangular keyboards connected by a See also:long expansible See also:bellows of many folds similar to that of the accordion
.
The keyboards are furnished with rows of knobs, which, on being pressed down by the fingers, open valves admitting the See also:air compressed by the bellows to the free reeds, which are thus set in vibration
.
These free reeds consist of narrow See also:tongues of See also:brass riveted by one end to the inside See also:surface of the See also:keyboard, and having their free ends slightly See also:bent, some outwards, some inwards, the former actuated by suction when the bellows are See also:expanded, the latter by See also:compression
.
The See also:pitch of the See also:note depends upon the length and thickness of the reeds, reduction of the length tending to sharpen the pitch of the note, while reduction of the thickness lowers it
.
The bellows being unprovided with a See also:valve can only draw in and emit the air through the See also:reed valves
.
In See also:order to produce the See also:sound, the concertina is held horizontally between the hands, the bellows being by turns compressed and expanded
.
The See also:English concertina, invented and patented by See also:Sir See also: The German concertina is not constructed according to this See also:system; its compass extends down to C or even Bb, but it is not provided with double action . It is possible on the English concertina to See also:play diatonic and See also:chromatic passages or arpeggios in legato or staccato See also:style with rapidity, shakes single and double in thirds; it is also possible to play in parts as on the pianoforte or organ and to produce very See also:rich chords . Concertos were written for concertina with See also:orchestra by See also:Molique and Regondi, a See also:sonata with piano by Molique, while Tschaikowsky scored in his second orchestral See also:suite for four accordions . The aeola, constructed by the representatives of the See also:original See also:firm of Wheatstone, is a still more artistically See also:developed concertina, having among other improvements See also:steel reeds instead of brass, which increase the purity and delicacy of the timbre . See also ACCORDION; CHENG; HARMONIUM; FREE-REED VIBRATOR . (K . |
