each stop usually controls one rank of pipes, although mixtures and undulating stops (such as the voix céleste) control multiple ranks. the name of the stop reflects not only the stop's timbre and construction, but also the style of the organ in which it resides. for example, the names on an organ built in the north german baroque style generally will be derived from the german language, while the names of similar stops on an organ in the french romantic style will usually be french. most countries tend to use only their own languages for stop nomenclature. english-speaking nations as well as japan are more receptive to foreign nomenclature. stop names are not standardized: two otherwise identical stops from different organs may have different names.
