| 介绍（英） | Chest organs are named because of their appearance. Housed in a chest, or box, the small organ can be moved around and set on a table, a stool, or the floor for performances. This example houses three ranks of pipes: a stopped wood 4' (Coppel), an open wood 2' (Holzprinzipal), and an open metal 1' (Octav).
