The open position of the guitar contains the notes of the open strings and the first three frets. Outlined next are the positions of these notes on the staff, tab, and on the fretboard. Also shown is an example of two separate octaves, an octave being two notes that have the same letter name and are eight consecutive notes apart.
A sharp (#) raises the pitch of a note by one semitone (1 fret). A flat (b) lowers the pitch of a note by one semitone. In music notation the # and b signs are placed before the note on the staff.
