 A portative organ or a positive organ (which are also, but imprecisely, known as "box", "trunk", and "cabinet" organs) can be used in a residential setting, but the notion of a residence organ strictly embodies a permanence of place that is belied by the notion of portability embodied by the portatives and positives.Similarly, a chamber organ (also known imprecisely as a "cabinet", "desk", or "bureau" organ) is in general a small organ for a room, but not necessarily for a room of someone's home.The overlap of definitions parallels an overlap of uses.
