Play this on each chord of the E Major chord scale. I will often only ascend the chord scale for arpeggios exercises like this. I also won’t use the higher version of E [0-14-14-13-0-0], but move to the basic E in first position following the D♯o.
Also, leaving out the thumb, we have i, m, and a. 3 things have 6 combinations. So, try the same string pattern, but play all 6. The patterns are i-m-a as shown, i-a-m, m-i-a, m-a-i, a-i-m, and a-m-i.
A good practice idea is to change the pattern on every chord. Repeat any of the patterns for the last couple of chords. Maybe ones that were more challenging.
Keep the driver knuckles over the string set we are picking. The space between your thumb & index will open up, & our elbow will move our hand over the next string set.
