reed stop

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. Music A stop on an organ made up of or controlling reed pipes.

Century Dictionary and Cyclopedia

1. n. In organ-building, a set or register of reed-pipes the use of which is controlled by a single stop-knob: opposed to fluestop. Each partial organ usually has one or more such stops, though they are less invariable in the pedal orgau 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 organ 1.) Reed-stops are specially valuable because of their powerful, incisive, and individual qualify, which is suited both for solo effects and for the enrichment of all kinds of combinations. The most peculiar reed-stop is the vox humana. A reed-stop is often called simply a reed.
