This vertical diagram is the most commonly used diagram for guitar. It is used to show the first four or five frets starting at the nut. The frets are actually the metal wires. However, the „fret area“ (the space between the nut and fret, or from one fret to the next) is generally referred to as the „fret.“ Frets are numbered from #1 as the lowest, all the way up the neck to the highest.

Sometimes a numeral will be used at the lowest fret in the diagram to indicate a different starting fret other than the first fret. This way, you can use this diagram to show any four or five consecutive frets on the guitar.
