when I started playing without a pic I would practice playing with my index finger, then, later with my index and middle. this excercise here will better prepare you for that 3 fingered galloping using your index,middle and ring finger. I started with the open chords cause to me they were the easiest to play with three fingers, whenever u here the 3 chords hit rapidly in this lesson use your ring finger,middle,and index (in that order)to hit each chord. the longer u practice this the faster u will get at it and youll start hearing the "gallop" sound. send me a message if u have any questions.
