Classical guitar 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 (formula_1), whose numeric value is about 1.059463. The twelfth fret divides the string in 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
Zero fret spaced properly. The strings rest atop the zero fret, which can be (but is not necessarily) higher than the other frets. It is claimed that with a zero fret, the sound of an open string more closely approximates the sound of a fretted string as compared to the open string sound on a guitar with no zero fret. Countering this claim are musicians who feel that a bone or even synthetic nut will enhance the overall tone of the instrument regardless of the string being played open or fretted. Since tone is so subjective, the two claims are likely to
