The open position of the guitar contains the notes of the open strings and the first three frets. The positions of these notes on the staff, tab, and the fretboard are outlined in the following diagram. 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. All the songs and examples in this book use notes in the open position.
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.
