try the pitch axis approach,
as explained in
this lesson assumes that you know how to play a major scale pattern 2
now, i’ve picked up where the video leaves off and also want to assume you know a major scale pattern 4 shape.
there are 5 essential major scale patterns that i recommend you learn.
start with patterns 2 and 4…they are very similar looking…and go nicely with the above video 
now, on with the exercise:
Play a E as a drone note
play E major scale pattern 2 — starting on 7th fret of A string.
that’s ionian mode
‘
now shift down 2 frets and play the D major scale pattern 2 —starts on 5th fret of A string,
that’s Dorian
now shift down 2 more frets and play the C major scale pattern 2–starts on the 3rd fret of the A string,
that’s Phrygian
now shift down 1 more fret and play the B major scale pattern 2—starts on the 2nd fret of the A string,
that’s Lydian
now shift down 2 more frets and you’re at open A, so instead,
just think of where Dorian was and go over 1 string to start your major scale, pattern 4 on the E string 5th fret.
that’s the Mixolydian mode
now shift down 2 more frets and play the G major scale pattern 4—starts on the 3rd fret of the E string,
that’s the Aeolian mode
now shift down 2 more fret and play the F major scale pattern 4—starts on the 1st fret of the E string,
that’s Locrian
