Anotations

Scope note:

Small organs housed in a compact, furniture-quality wood cabinet, usually with one manual and no pedal keys, the wind being pumped into the pipes by the player's foot. Popular for domestic use in Europe and North America from the 17th to the 19th century, they were often made to resemble other pieces of furniture, such as tables, bureaus, and desks.
