24 DICTIONARY OF ORGAN STOPS.
Free-reed Clarinet (Stahlhuth).
with conical bodies at Aix-la-
Chapelle Kurhaus (Stahlhuth).
It was a good representation of
the orchestral instrument—not
necessarily therefore all that
could be desired in an organ
stop, for the latter is more
consistent and regular in tone
throughout the compass than
the former. The author has
in his possession a replica of
one of these pipes kindly made
for him by Herr Stahlhuth.
The Clarinet is a stop of
"short length." By means of
a long tongue it is caused to
speak at unison pitch, though
the length of the pipe is only
a little more than that of those
of a 4 ft. stop. (See remarks
under Reed). Its peculiar
hollow tone is due to the
fact that reed tubes of cylin-
drical form have the property
of strongly reinforcing the
odd-numbered partials, those
yielded by a stopped pipe
As a matter of fact the evennumbered
partials are not
usually entirely eliminated
from a Clarinet, especially
from the lower notes. In the
case of the Vox Humana the
pipes, though generally cylin-
drical, are not ordinarily of
sufficient length to exert much
influence on the tone, to which
fact, and to the subdued char-
acter of the said tone, is at-
tributable the incompatibility
of this stop to the rule above
enunciated. Similarly the short
pipes of the Physharmonika
