Standard tuning strings. This is done to simplify fingering. A few guitarists, mostly those using tapping, play without this interval, instead tuning in all fourths; thus on a six-string guitar the top two strings become C and F instead of B and E. Other unusual tunings include all major thirds, all minor thirds, and various other choices. In standard notation, the guitar sounds one octave lower than it is written. This is to avoid switching between treble and bass clef, or using ledger lines or 8vb, since it is very common to play past the 12th fret on the E string (E)
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.
