beautiful and mellow in quality. In the tenor it affords a good represent-
ation of the Orchestral Horn. The languid is inverted, being flat at the
top and bevelled away underneath (see Inverted Languid, Stops with).
The upper lip is arched, left slightly rounded (i.e., not definitely flattened
into a bay-leaf), and not bevelled. A specimen in the author's possession

(1) A reed stop invented by Mr. William Hill. Of smaller scale and
somewhat smoother tone than the Horn, it is softer and rounder than the
Trumpet. The pipes are of inverted corneal shape, and the tongues thick.
Like all chorus reeds the Cornopean is all the better for a fairly heavy
wind pressure. This class of stop was practically perfected by Willis,
whose work exhibits as great an improvement on that earlier in vogue, as
did the latter on that of the old English builders. A harmonic treble is
absolutely essential for the best results. A smooth-toned reed of this
description is more effective in the Swell than a Trumpet. (2) Formerly
in Germany the name Cornopean was sometimes given to a large-scaled
flue stop of horn-like tone, a variety of Cor de Nuit.
Corroborating Mixture—See Compensation Mixture.
Coupler—(1) A mechanical device for uniting various departments
or keys of the organ together.
Couplers are comprised under the following headings :
—
(a) Uniting
two departments—Swell to Great, Swell to Pedal, etc. (b) Octave and Sub-
octave Couplers, depressing the notes at intervals of an octave respectively
above or below the chord held. Thus, if the chord C E G be held
on the Swell organ, and the Swell Octave Coupler be drawn, the said
C E G will be duplicated an octave higher. This type of coupler may
further be divided into two Classes :— (i) Those couplers acting on one
manual only, or on the pedal, as described above, (ii) Those acting on
separate manuals—Swell to Great Sub-octave, Swell to Great Octave. *
The Octave Coupler is sometimes named Super-octave Coupler in
contradistinction to the Sub-octave Coupler. Strictly speaking this is a
•The above is the terminology usually employed. The author must, nevertheless,
express his strong preference for the style : Swell Sub-octave to Great, Swell Octave to
Great—as being more lucid.
