A house organ is a mostly smaller pipe organ (in contrast to the home organ ) that is located in a residential building (up to the castle) or a comparable building. In principle, the term “house organ”, in contrast to the positive , is often understood to be a permanently installed instrument; in practice, cabinet-like house organs are often given the same name. Due to the significantly smaller installation space compared to churches, concert halls and comparable rooms, there are special structural requirements. In particular, the pipes require significantly less volume. The typical timbres of the registers should be preserved as far as possible.

The limited space requires a very compact design. The longest pipes of an open 8 'register or a covered 16' register may have to be installed horizontally or they are cranked . In the covered 16 'register, often only the 12 lowest pipes are built and the pipes from a covered 8' register are used for the higher notes per octave extension . In the case of an open 8 'register, the lowest notes are alternatively executed as Gedack, reed flute or pointed, or the pipes of a covered 8' register are used for these notes, i.e. H. these pipes are used by both the open 8 'register and the covered 8' register. In the case of reed registers with the full cup length, the lowest position is often half the cup length, which is often supported by reasons of space and sound. In the simplest case, the house organ only has a manual with a few registers, a pedal is then just attached. House organs usually have one or two manuals with two to ten registers each and a pedal with one or two registers. The sensible upper limit is around 20 registers spread over two manuals and pedal. To expand the sound possibilities, the manual registers are often divided into bass and treble on smaller instruments.
