Editing C (musical note) (section)

===Other octaves===
In vocal music, the term ''High C'' (sometimes called ''Top C''<ref>{{cite web|url=https://www.nytimes.com/1979/11/04/archives/music-view-birgit-nilsson-the-return-of-a-supersoprano-music-view.html|title=Birgit Nilsson – The Return of a Super-Soprano|author=Harold C. Schonberg|author-link=Harold C. Schonberg|work=[[The New York Times]]|date=November 4, 1979}}</ref>) can refer to either the soprano's [[scientific pitch notation|C<sub>6</sub>]] (1046.502&nbsp;Hz; {{prime|c}}{{prime}}{{prime}} in Helmholtz notation) or the tenor's C<sub>5</sub>; soprano written as the C two ledger lines above the treble clef, with the tenor voice the space above concert A, sung an octave lower. Sometimes written with “8v” below the treble, to represent the octave (8 tones in a major scale).

''Tenor C'' is an [[organ builder]]'s term for ''small C'' or C<sub>3</sub> (130.813&nbsp;Hz), the note one [[octave]] below middle C. In older stoplists it usually means that a [[Organ stop|rank]] was not yet full compass, omitting the bottom octave, until that octave was added later on.
