Anyone have advice for strumming just 2 or 3 strings without strumming the adjacent strings? I am learning to play Hole Hearted and it seems like a constant strumming pattern on just a couple strings near the beginning of the song. The strings I'm trying to strum are the A and D strings. But my problem is that I am hitting most all the strings with my pick. I have the general basics of strumming down but this technique is really challenging me.
