Editing Inharmonicity (section)

==Mode-locking==

Other stringed instruments such as the violin, viola, cello, and double bass also exhibit inharmonicity when notes are plucked using the [[pizzicato]] technique. However, this inharmonicity disappears when the strings are bowed, because the bow's stick-slip action is periodic,<ref name="complexity">Neville H. Fletcher (1994).

As a result, the operating mode of a bowed string playing a steady note is a compromise among the tunings of all of the (slightly inharmonic) [[string resonance (music)|string resonances]], which is due to the strong non-linearity of the stick-slip action.<ref name="How"/>  Mode locking also occurs in the [[human voice]] and in [[reed instrument]]s such as the [[clarinet]].<ref name="complexity"/>
