The following exercise will show you
how from learning one scale shape you can move this same shape around the
neck of the guitar to give you other scales in other keys.
The first scale is the G Major
Scale. The 2nd scale is the A Major Scale.
The 3rd scale is the F Major
Scale.
Click below for an example of the above
scales.
As you can see by the above example, if
you take a scale starting on the E string and move it up or down the fret
board you are playing the same shape but the first note (the ROOT note)
determines what the name of the scale is.
If we look at the chart below we will
see all the names of the notes on the E string, and by picking a fret to
start the scale on will determine the name of the scale.
So, by learning one scale pattern you
now have learned every major scale starting on the 6th string E. This
principle will work for all scales starting on the E string whether they are
major, minor, blues, pentatonic etc, just learn the pattern and move it
around the guitar neck.
Below shows some scale diagrams to
demonstrate the how the patterns look the same but when you move them over
the fret board you are playing different scales.
Note that the diagrams below show
another way to play the 3 note per string scales shown above, the notes on
the G, B and E strings are played in another position but they are the same
notes as the scales above.
A Major scale B
Major scale C Major
scale D Major scale E major scale F Major
scales G Major scales
(the numbers below the diagrams show the
fret which the root note starts).
