Note: The scales in this lesson are all G scales, but you can move the pattern all the way up the strings. I will use abbreviations for whole step and half step in this lesson. Whole step is represented by 'W', and half step by 'H'. A whole step means to go up 2 frets, and a half step means 1 fret.
