Fretting Notes (frɛ́tɪŋ nóts) is a term used to describe when a guitar player presses his/her fingers down on the strings of a guitar until is the strings press against the small metal bars laid into the neck, know as the frets.

Fretting a note changes the vibrating length of the string, which changes the tone made when the fretted string is plucked or strummed. Therefore, unlike other stringed instruments that do not use frets such as violins and cellos, frets are also used as placeholders for every note on a guitar.
