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
Rocksmith rectangles, matching the color of the guitar string(s) to be held down, move from the background to the foreground along numbered lanes reflecting the fret position. The notes turn 90 degrees at the moment that they should be strummed; additional markers are provided to help with timing of future notes. Additionally, the game shows an ideal position for the player's hand on the fretboard for the current segment of the song, moving this up and down as necessary. Lyrics to the song, if any, are shown in a karaoke-style under the background note pattern, but otherwise do not impact gameplay.
