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
Rhythm game accessories existing "Rock Band 2" drum sets. For the pro guitar mode of "Rock Band 3", a pro guitar controller is required. Unlike standard guitar controllers, pro guitars allow input of any fret/string combination, allowing accurate simulation of a real guitar. The Fender Mustang Pro Guitar controller, which is based on the Fender Mustang, has 102 buttons along its neck which simulate holding the guitar strings against the fretboard. All six strings are represented along 17 different frets. In order to simulate picking/strumming, the Mustang pro controller features a "string box" located on the body of the controller (around the position
