Although, I don’t do much lead improv from these scale patterns, it is important to cover these major scale patterns.  These are all in the key of G and are movable to other positions for other keys. Practice and learn the shape/pattern of the scale, then move it up and down the fretboard to other keys. “*” Represent the root note.

G Major Scale – E String Fret 3

G Major Scale – A String Fret 10

Practice this scale ascending and descending, and move it to other positions on the fretboard. The first group is the scale itself. The second group are additional notes in the scale below and above.

    *              *              *               *

G Major Scale – E String 15 Fret

Practice this scale ascending and descending and then move it to different locations on the fretboard after familiarizing yourself with the shape.

Other Major Scale Shapes

There are other major scale shapes, one commonly referred to as the diagnal form, but I prefer to show you this with the diagnal form of the pentatonic scale.

As I mentioned previously, I do not do much lead improv from these scales, but knowing their positions, helps me when I’m playing lead across the fretboard.

Let me know if you have any questions or comments.
