I thought I got chords, until I attemted them on guitar. How do you play lets say a major triad?... for example, they come out to no more than 2 strings. Also, I looked at tabs to give me a better idea, and they all depicted them as completely different than the root, 3 and 5. Also, trid fingerings I can find have 4 and 5 strings played at once. What am I missing?
