Popular from the 1870s through the early 1900s, organettes are mechanically operated reed organs, designed primarily for home use. Usually smaller than keyboarded parlor organs, most were inexpensive and cranked by hand. Music was supplied on paper discs, sheets, rolls, or books, metal discs or rolls, wooden rollers or barrels, and tunes lasted from a few seconds to several minutes. Popular models offered over a thousand tunes, and hundreds of models were manufactured, even though many were produced for only a short time.
