reeds top (redstop)

In organ - building, a set or register of reed-pipes the use of which is controlled by a single stop-knob: opposed to flue stop. Each partial organ usually has one or more such stops, though they are le invariable in the pedal organ than in the others. They are generally intended to imitate some orchestral instrument, as the trumpet (usually placed in the great organ), the oboe (usually in the swell organ), the clarinet (usually in the choir organ), the trombone (usually in the pedal organ), the cornopean, the clarion, the contrafagotto, etc. They may be of eight-feet, four-feet, or sixteen-feet tone. (See organ1.) Reed-stops are specially valuable because of their powerful, incisive, and individual quality, which is suited both for solo effects and for the enrichment of all kinds of combinations. The most peculiar reed-stop is the vox human a. A reed-stop is often called simply a reed. b, stop-rail; b', stop-knob; b", stop-shank; n, stop-arm; n', rock lever, connected at n" to the lever, the latter being pivoted to a rail at s.

In organ -building, the reed-stops of an organ, or of a partial organ, taken collectively: opposed to flue - work. in the ba after the fingers have left the s, or for emphasizing the treble, are sometimes introduced. Pianofortes are made with a harmonium attached (sometimes called an æolian attachment ). The reed-organ has become one of the commonest of musical instruments. Its popularity rests upon its capacity for concerted music, like the pianoforte and pipe-organ, combined with simplicity, portability, cheapne , and stability of intonation. Ar tistically regarded, its tone is apt to be either weak and negative or harsh and unsympathetic. A variety of recent invention, the vocalion, has a remarkably powerful and mellow tone.
