| 介绍（英） | The chamber organ is a moderately-sized piped organ. It typically has a single manual, a limited number of stops, and a limited pedalboard or no pedals at all. It is generally intended for use in small chapels, in homes, or other intimate rooms. As it is capable of long sustained tones, it is sometimes preferable to harpsichord as a continuo instrument in chamber ensembles.
Such instruments might also be used in small churches, like those found in small towns and villages throughout the United States in the nineteenth century. Chamber organs were largely usurped by reed organs after the middle of the century.
