Guitar Frets are laid out to accomplish an equal tempered division of the octave. Each set of twelve frets represents an octave. The twelfth fret divides the scale length exactly into two halves, and the 24th fret position divides one of those halves in half again. The ratio of the spacing of two consecutive frets is formula_1 (twelfth root of two). In practice, luthiers determine fret positions using the constant 17.817—an approximation to 1/(1-1/formula_1). If the nth fret is a distance x from the bridge, then the distance from the (n+1)th fret to the bridge is x-(x/17.817). Frets are available in
Power Gig: Rise of the SixString ships with a 2/3 scale six-string electric guitar, designed to be usable with "Power Gig" and other games in a similar fashion to a standard guitar controller. The edge of its fretboard contains colored markings corresponding to in-game notes. In the game's basic mode, the player must hold down any string(s) in the colored fret areas that match the displayed note patterns on screen, and then strum the strings in time. In the game's "Power Chord" mode, the colored notes on screen are replaced with colored numbers from 1 to 6, representing which string(s) must be held down in the
