Hey there GMC! I am a beginner and have only been playing guitar for a few weeks now. I have been working on how to play power chords. My problem is that whenever I try to play one I either don't strum the strings fast enough, making it sound like 2 separate notes, or I strum and then hit a string I wasn't supposed to hit with my downstroke. Any tips on how I can correct this problem and how to strum them correctly?
