Editing Multiphonic (section)

===Vocal multiphonics===
The technique of producing multiphonics with the voice is called [[overtone singing]] (typically with secondary resonant structure) or throat singing (typically with additional tones from throat trills).

There is another technique done in whistling, where whistlers hum in their throats while whistling with the front parts of their mouths. This is well known for achieving a spacey "ring modulation" sound (e.g. by [[Jim Carrey]] in ''[[The Truman Show]]'').{{Citation needed|date=September 2019}} All three vibrations—whistle, voice and throat trill—can be combined also.
