26 DICTIONARY OF ORGAN STOPS.
the stopper relieves the tone of undue development of the twelfth, and a
reedy, growling tone, by no means unpleasant, and even somewhat sug-
gestive of the Clarinet (by reason of the odd-numbered partials being
mainly present), is produced. Light winding is advisable. The stop was
probably invented, and certainly perfected, by Messrs. Gray & Davison, in
whose work many examples are still to be found. There is a successful
instance in the Great at St. Joseph (R.C.), Stockport. Bishop also used
the stop. A Swell organ specimen of his measured at the mid. C pipe
i^ in. x i^ in., the height of the mouth (to top of arched lip) £ in. (very
low, under a fourth), the hole in stopper J in. The tone is very difficult
to preserve, and to control, throughout the compass. Christ Church,
Macclesfield ; Centenary Chapel, Boston (Lines.) ; St. Margaret, Brighton
Bombay Town Hall (Bishop), contain examples by Gray and Davison.
The term "Clarinet Flute" is often merely a misnomer for Rohrflote.
Clarion— Clairon, Clarin, Clarino. (It.) Clarino = a small Trumpet.
4 ft. on manual and pedal.
An octave reed, varying considerably in power and quality according
to the 1 6 ft. and 8 ft. stops with which it is associated. Practically an
octave Trumpet. The Clarion should invariably be harmonic in the
treble, as thereby not only is the quality improved and the wearisome
clang removed, but it is also more likely to stand in tune—a virtue
generally beyond the attainments of the true-length pattern. Unless of
harmonic construction the top few notes are, as a rule, formed of flue
pipes, though Willis carried his reeds right through. Tuba Clarion is
an octave Tuba.
Clarion Mixture—This stop was used by Messrs. Walker at a time
when they had discarded 4 ft. reeds. It was therefore intended to
add considerable brilliancy to full organ.
The Clarion Mixture was of III ranks, heavily blown, and voiced to
considerable power. Had it been of V or VI ranks it would probably
have been less obtrusive, because less bare. See Schreier. Holy Trinity,
Sloane Street, S.W. ; St. Matthew, Northampton; St. John the Divine,
Kennington, S.W.
Clavaeoline— 16 ft. ; 8 ft.
A free (harmonium) reed introduced into the organ by Beyer, of
Niirnberg, in 1830. The tongues were of nickel silver. It was similar
in all respects to its successor, the Physharmonika, save that there existed
no device for securing expressive effects by varying the wind pressure.
Fulda; St. Wenzeslaus, Naumberg; Perleberg; Salzwedel (Turley, 1838).
The Clavaeoline has also been made as a soft-toned free reed, with bellshaped
pipes.
