1 2 in. wind, Weigle) are to be found <strong>stops</strong>, the treble pipes <strong>of</strong> which are<br />
<strong>of</strong> triple length. The Tuba is sometimes enclosed in a swell box. In a<br />
non-resonant building there is no doubt but that the practice is conducive<br />
to greater efficiency. There are good instances <strong>of</strong> enclosed Tubas at<br />
St. Alban, Holborn (Willis) ; Burton Parish Church (Norman & Beard).<br />
The pipes <strong>of</strong> the Tuba are <strong>of</strong> inverted conical shape, those in the top<br />
octave being occasionally surmounted by a bell. The pipes are now <strong>of</strong>ten<br />
made <strong>of</strong> the thick, "special," unplaned metal referred to under Diapason.<br />
Tuba<br />
(treble pipe).<br />
In Germany the name Tuba is given<br />
to a powerful Trumpet as well as to <strong>stops</strong><br />
voiced after the Willis pattern (as by<br />
Stahlhuth, Weigle and a few others). It<br />
is now generally admitted that Tubas<br />
should dominate the <strong>organ</strong>, after the<br />
analogy <strong>of</strong> the orchestral " brass.'' Those<br />
acquainted with the imposing effect <strong>of</strong><br />
the large Willis Tuba, with Double Tuba<br />
and Tuba Clarion (harmonic, <strong>of</strong> course)<br />
used in full <strong>organ</strong>, will notice the brilliancy<br />
imparted by the Tuba Clarion, the perfect<br />
finish and balance it adds to the ensemble.<br />
When both cannot be afforded, the Double<br />
Tuba is, <strong>of</strong> course, preferable to the Tuba<br />
Clarion. See Double-tongued Reed,<br />
Tuba Minor, Tuba Sonora, and illustra-<br />
tions under Reed. Scale.—The following<br />
are the measurements <strong>of</strong> the Tuba Mirabilis<br />

Beard):— CC, 7 in.; T. C, in. ; 6f Top<br />
C., 4^ in. From tenor C to F sharp (31<br />
notes above) the pipes are <strong>of</strong> double<br />
length. From G to top C the tubes are ixjXn.<br />
<strong>of</strong> triple length— in <strong>organ</strong>- building phrase- (top octave).<br />
ology "an octave and a fifth longer" than<br />
the note they give.<br />
Tuba Clarion—4 ft. An octave Tuba (g.v.).<br />
TUBA MAGNA—(Lat.) Magnus = great. See Tuba Major.<br />
TUBA MAJOR—Tuba Magna. (Lat.) Major = greater. Either (1) a<br />
Double Tuba, or (2) an 8 ft. Tuba <strong>of</strong> full scale and power, a Tuba<br />
Mirabilis.<br />
In the latter sense the name Tuba Magna is applied to a reed at<br />
St. Saviour's Collegiate Church, Southwark (Lewis).
