I may also use ''fretboard maps '' and ''chord charts''. These take the below form, very similar to tablature (or tab):

Each '''line ''' of text represents a string. The '''vertical bars''' represent the physical frets. (You fret "behind" the fret like in the maps above; see [[Basic Technique]].) The last '''line of text with the numbers ''' may or may not be present. It specifies the fret numbers. Since fretboard maps and chord charts are patterns that can be used on any group of frets on the guitar, they are not necessarily tied to any particular fret numbers, which is where their power lies. The vertical bars represent division between frets.

The first figure is a ''fretboard map '' or ''scale map/chart/pattern''. The '''x's ''' represent frets on that string that are part of whatever scale is being illustrated. The '''R's ''' indicate ''root notes '' of the scale. The '''*'s ''' indicate that these are the same note, but can be played in either location. These maps are a more compact way than tab to demonstrate the fretboard pattern of a particular scale. The chord chart in the middle is exactly the same thing, but is not meant to simply indicate the member notes, but how to finger all the notes at the same time. o = open, i = index, m = middle, r = ring, p = pinky, t = thumb, ) = indicates to "barre" your index finger (discussed later).

The ''chord chart'' in the middle is exactly the same thing, but is not meant to simply indicate the member notes, but how to finger all the notes at the same time.  {| class="wikitable"|-! Symbol !!
