In addition to being thought of as a wind or keyboard instrument, there's another component to all pipe organs that makes each of them unique in a way (almost) no other instrument is - the room they are installed in. With very rare exceptions, pipe organs aren't mobile, so the acoustics of the room matter almost as much as the pipes do.
