Editing Overblowing (section)

==Pipe organ==
Some [[organ pipe]] ranks are designed to be overblown. For instance, a given pipe of the harmonic flute [[Organ stop|stop]] is twice the length of pipes of other stops designed to sound the same pitch.<ref>{{cite web |url=http://www.organstops.org/h/HarmonicFlute.html |title=Harmonic Flute |website=Encyclopedia of Organ Stops |access-date=2017-08-22}}</ref> When such a pipe is overblown, it sounds a fundamental tone one octave higher than other pipes of its length. For instance, a harmonic flute pipe that is 16 feet long is designed to sound the same note as most 8-foot pipes.<ref>{{cite book |last=Barnes |first=William Harrison |year=1930 |title=The Contemporary American Organ: Its Evolution, Design and Construction |url=https://catalog.hathitrust.org/Record/001458172 |location=New York |publisher=J.
