We’re now going to look at 4 simple fretting exercises using one finger (The Forefinger to be precise). The aim here is to ensure every note rings out very clearly –so for the moment, just forget about the speed element. This will come with time.
Here are the exercises as explained by Andy:
Exercise 1:
Starting at the bottom E string fret the 1st, 2nd, 3rd, 4th and 5th frets. Repeat for the A, D, G, B (Only to the 4th fret) and E strings
Exercise 2:
Repeat Exercise 1 except this time starting at the 5th fret of the top E string. (The A note).
Exercise 3:
Repeat Exercise 1 except this time, include the open strings
