DICTIONARY OF ORGAN STOPS. 87<br />

Harmonic Flute, and a liquid and bright 4 ft. Great stop.<br />

The former, which is voiced on a heavy wind pressure, is<br />

made <strong>of</strong> extremely thick and weighty metal, and provided with<br />

leathered lips.<br />

In many <strong>of</strong> the larger instruments <strong>of</strong> Cavaille'-Coll, the Solo<br />

Harmonic Flutes frequently sound distressingly coarse when<br />

heard close to, a quality <strong>of</strong> tone probably due to the sharp thin<br />

lips and thin tin pipes he, in common with the majority <strong>of</strong> French<br />

builders, employed. When heard at a distance this disagreeable<br />

feature is not noticeable, indeed the stop there probably sounds<br />

all the better for this boldness <strong>of</strong> treatment. In the author's<br />

estimation, however, Messrs. Walker's <strong>stops</strong> <strong>of</strong> this class are<br />

preferable. Yet, so far as large buildings are concerned, if the<br />

provision <strong>of</strong> both varieties <strong>of</strong> Harmonic Flute is not contemplated,<br />

the fuller toned type <strong>of</strong> stop will probably be found the more<br />

effective. Derby Road Church, Nottingham (imported from<br />

Cavaille-Coll by Conacher) ; Albert Hall, Sheffield ; Town Hall,<br />

Manchester (Cavaille'-Coll). The author, also, has in his pos-<br />

session a typical Harmonic Flute pipe made by this firm. See<br />

also Flute Octaviante.<br />

The pipes <strong>of</strong> the Harmonic Flute are variously made with and<br />

without ears. Occasionally they are furnished with long ears for<br />

tuning purposes (see Bell Gamba). Roughly speaking, the<br />

hole or holes rendering the pipes harmonic may be pierced<br />

anywhere in the middle portion <strong>of</strong> the pipe ; but the position in<br />

which they are most conducive to facility <strong>of</strong> speech is supposed<br />

by some voicers to be at a distance <strong>of</strong> two-fifths up the pipe.<br />

The Harmonic Flute is copiously winded, though no increased<br />

pressure is necessary save in the case <strong>of</strong> solo varieties. The<br />

pipes are <strong>of</strong> harmonic construction variously from fid. G, mid. C<br />

and F upwards, the bass pipes being voiced " tubby " to match,<br />

and therefore sometimes known by the classical (!) appellation <strong>of</strong><br />

"Tubs." Some builders cause the upper lips <strong>of</strong> Harmonic Flute<br />

pipes to protrude considerably, the process being known technically<br />

as '.' lifting " the lip. An example <strong>of</strong> a stop so treated may be<br />

seen at Moreton, Dorset (Conacher). Scales.—Harmonic Flute,<br />
