Editing Twelve-string guitar (section)

=="Chorus" effect==

The double ranks of strings of the 12-string guitar produce a shimmering effect, because even the strings tuned in unison can never vibrate with precise simultaneity—that is, they vibrate out of [[phase (waves)|phase]]. The result to the ear is a sound that seems to "shimmer", which some describe as resembling strings that are slightly detuned. The interference between the out-of-phase vibrations produces a phenomenon known as a [[Beat (acoustics)|beat]] that results in a periodic rise and fall of intensity which is, in music, often considered pleasing to the ear. [[Pete Seeger]] described the distinctive sound of the 12-string guitar as "the clanging of bells."<ref>{{cite web |last1=Simmons |first1=Michael |title=The origins of Twelve String Power |url=http://www.frets.com/FretsPages/History/12string/12stOrigins.html |website=frets.com |publisher=Acoustic Guitar Magazine |access-date=16 January 2019}}</ref><ref>{{cite book |last1=Tolinski, di Perna |title=Play It Loud: An Epic History of the Style, Sound, and Revolution of the Electric Guitar |date=2016 |publisher=Knopf Doubleday Publishing Group |location=New York, NY |isbn=978-0385541008 |edition=Hardcover |url=https://books.google.com/books?id=o3J_CwAAQBAJ&q=Pete+Seeger+described+the+distinctive+sound+of+the+12-string+guitar+as+%22the+clanging+of+bells&pg=PT161 |access-date=16 January 2019}}</ref><ref>{{cite web |last1=Bogdal |first1=John |title=12-String Guitar: From the Street to the Stage |url=https://www.stringjoy.com/12-string-guitar-street-stage/ |website=Stringjoy.cm |publisher=Stringjoy, LLC |access-date=16 January 2019}}</ref>
