====Keyboards====
Keyboards played by the hands are known as ''[[manual (music)|manuals]]'' (from the [[Latin language|Latin]] ''{{lang|la|[https://en.wiktionary.org/wiki/manus mănus]}}'', meaning "hand"). The keyboard played by the feet is a ''[[Pedal keyboard|pedalboard]]'' (from the [[Latin language|Latin]] ''{{lang|la|[https://en.wiktionary.org/wiki/pes#Latin pēs], pĕdis}}'', meaning "foot"). Every organ has at least one manual (most have two or more), and most have a pedalboard. Each keyboard is named for a particular division of the organ (a group of ranks) and generally controls only the stops from that division. The [[range (music)|range]] of the keyboards has varied widely across time and between countries. Most current specifications call for two or more manuals with sixty-one notes (five octaves, from C to c″″) and a pedalboard with thirty or thirty-two notes (two and a half octaves, from C to f′ or g′).{{efn||name=Helmholtz}}<ref>[http://www.agohq.org/guide/pages/pages_5_5/frameset01.html Pipe Organ Guide] {{webarchive|url=https://web.archive.org/web/20070927154656/http://www.agohq.org/guide/pages/pages_5_5/frameset01.html |date=27 September 2007 }}.
