The guitar scales at GOSK are shown in five different positions, which allow you to cover the whole fretboard. Some of the scales have an additional sixth position, a 3-notes-per-string pattern, for fast runs.
How to read the scale diagrams?
The six horizontal lines represent the strings. The first string (highest tone) is on top and the sixth string (lowest tone) is at the bottom. The vertical lines represent the frets. The numbers below the diagram indicate which finger to use on each fret (1 is the index finger).
The shows you where to put your fingers. The is the root of the scale (the root gives the scale its name; i.e. if the note E is the root of a harmonic minor scale, the scale is an "E harmonic minor").
