I'm not really sure how to play notes on adjacent strings at the same fret especially in faster passages. What I'm wondering is if I should try to "jump my finger" and try to hit the second note with my finger tip or flatten my finger and play the second not with the underside of my finger. That is when playing a note on a lower string to a higher one. When going from higher to lower how do I do this? Is there a special technique to doing this when you are shifting from one string to the next when you are changing strings back and forth on every beat? Like should I hold both down like a chord? I hope I am clear with the question.
