    *Notes:  Unlike other listings ordered by number of ranks or "stops", we count only genuine speaking pipes. Listings by ranks are not as reflective of an organ's true size, as some ranks may be of small compass (i.e., having fewer than 61 pipes per rank). For example, a 16' string rank may just extend to Tenor C, not Low C.  Also, our list does not count "digital" (i.e., electronic) "ranks" — thus, the U.S. Naval Academy Chapel's 268-rank organ having 110 genuine pipe ranks is not among the largest pipe organs listed here.
