It is a scale diagram of guitar which a pro teaches.
There are 61 kinds of diagrams.
If all are memorized, all the scales will come to burst throughout a fingerboard

Major Scale - 14 Position
Pentatonic Scale - 5 Position
Harmonic Minor Scale - 7 Position and more.
Melodic Minor Scale - 7 Position
Diminish Scale
Combination Of Diminish Scale
Whole Tone Scale

and Traid Arpeggio, 7th Cord Arpeggio.

If it is a jazz guitarist, it is necessary to memorize all the positions.
I think that I want the guitarist of a Rock or Pop to keep in mind a major scale and Pentatonic scale and the harmonic minor scale with easy Fingering.

The scale practice can train not only training of a motion of a finger but an ear.

Please practice every day and memorize.

Keys are only C and Am.

If it memorizes, by oneself, please transpose to other keys and practice.
