====Frets====
{{Main article|Fret}}

Frets are the metal strips (usually nickel alloy or stainless steel) embedded along the [[fingerboard]] and placed at points that divide the length of string mathematically. The strings' vibrating length is determined when the strings are pressed down behind the frets. Each fret produces a different pitch and each pitch spaced a half-step apart on the 12 tone scale. The [[ratio]] of the widths of two consecutive frets is the [[twelfth root of two]] (<math>\sqrt[12]{2}</math>), whose numeric value is about 1.059463. The twelfth fret divides the string into two exact halves and the 24th fret (if present) divides the string in half yet again. Every twelve frets represents one octave. This arrangement of frets results in [[equal temperament|equal tempered]] tuning.
