Editing Audio feedback (section)

===Pitched feedback===<!--[[Pitched feedback]] redirects directly here-->
Pitched melodies may be created entirely from feedback by changing the angle between a guitar and amplifier after establishing a feedback loop. Examples include [[Tool (band)|Tool]]'s "[[Jambi (Tool song)|Jambi]]", [[Robert Fripp]]'s guitar on [[David Bowie]]'s "[[Heroes (David Bowie song)|Heroes]]" (album version), and [[Jimi Hendrix]]'s "[[Third Stone from the Sun]]" and his live performance of "[[Wild Thing (The Troggs song)|Wild Thing]]" at the [[Monterey Pop Festival]].<ref name="Hodgson" />{{rp|119}}

Regarding Fripp's work on "Heroes":
{{blockquote|Fripp [stood] in the right place with his volume up at the right level and getting feedback...Fripp had a technique in those days where he measured the distance between the guitar and the speaker where each note would feed back. For instance, an 'A' would feed back maybe at about four feet from the speaker, whereas a 'G' would feed back maybe three and a half feet from it. He had a strip that they would place on the floor, and when he was playing the note 'F' sharp he would stand on the strip's 'F' sharp point and 'F' sharp would feed back better. He really worked this out to a fine science, and we were playing this at a terrific level in the studio, too.|[[Tony Visconti]]<ref>Buskin, Richard (October 2004).
