G5 C5 A5 D5 Progression
Play this progression using the movable R5 shape based on E.
To help remember, we can write the number of the fret for the 1 finger, as shown.
And, if needed, we can practice just the one finger; then add the 3 finger [or pinky, if we are using it]. We can also use our 1-3-4 [R-5-R] fingering, or the drop D version, but the numbers above will be off 2 frets for string 6.
