DICTIONARY OF ORGAN STOPS. 169<br />

V.<br />

Varitono— (Sp.) = Baryton.<br />

VENTIL<br />

A valve controlling the passage <strong>of</strong> wind to any particular department or<br />

group <strong>of</strong> <strong>stops</strong>. Having cut <strong>of</strong>f the wind supply to certain <strong>stops</strong> by means <strong>of</strong><br />

such a contrivance, it is evidently at the option <strong>of</strong> the performer to prepare<br />

any particular combination <strong>of</strong> such <strong>stops</strong> as he may desire, bringing them<br />

into operatioti by means <strong>of</strong> the ventil at the desired moment. This ventil<br />

control is normally employed in France. One <strong>of</strong> the main objections to<br />

the system rests in the fact that it imposes a constant tax on the player's<br />

memory—already sufficiently overburdened. It likewise involves a con-<br />

siderable amount <strong>of</strong> hand registration. The English system, dispensing.<br />

with ventils, secures rapid and indicatory stop manipulation by means <strong>of</strong><br />

pistons. On the Continent, and sometimes in America, the combination<br />

pistons serve to throw the ordinary stop action out <strong>of</strong> gear, indicating this<br />

by remaining in when once pressed. The movement <strong>of</strong> a special negative<br />

or release piston (see Ausloser) once again restores the action <strong>of</strong> the stop<br />

knobs or keys. This system, however, is rapidly being discarded in<br />

America in favour <strong>of</strong> the English method <strong>of</strong> so arranging the pistons as to-<br />

throw out the stop-knobs. Mr. Hope-Jones' "Stop-switch," and Messrs.<br />

Hill & Sons' " Ventil-switch " are really ventils in the sense that they cut<br />

<strong>of</strong>f the electric current from the stop action, thus enabling a combination<br />

<strong>of</strong> <strong>stops</strong> to be prepared beforehand and switched on at desire. Mr. Casson's<br />

Manual Help is also a variety <strong>of</strong> ventil switch, admitting <strong>of</strong> two or more<br />

departments <strong>of</strong> the <strong>organ</strong> being controlled by one manual.<br />

VIBRATO—See Tremulant.<br />

Viejos—A Spanish stop. Viejos = the eyebrows.<br />

The stop is said to derive its name from the shape <strong>of</strong> the cover or plug"<br />

at the top <strong>of</strong> the pipe. (Hamilton's " Catechism <strong>of</strong> the <strong>Organ</strong> "). Former<br />

<strong>organ</strong> at Seville Cathedral.<br />

VIENNA FLUTE—Wienerflote. Wien = Vienna. 8 ft. ; 4 ft.<br />

Locher remarks that the name Wienerflote lacks all historical andi<br />

etymological foundation. See Flauto Traverso.<br />

Vigessima-quarta—(Lat.) = Twenty-fourth.<br />

Vigessima-nona— (Lat.) = Twenty-ninth.<br />

Vigessima-secunda—(Lat.) = Twenty-second.<br />

Vigessima-sexta—(Lat.) = Twenty-sixth. Found in ancient Italian-<br />

<strong>organ</strong>s.
