So I went onto play some chords again tonight, just moving back and forth from E to A-minor. Each finger just moves one string down to switch back and forth between these. It sounds pretty easy, but when I was playing along with the game, it kept telling me that I was missing chords. I'm not sure if I wasn't pressing my fingers hard enough on the frets or what, but something must not have been right for the ones I missed. I played the same two strings over and over to practice and eventually got a little better, but still didn't make 3 stars on the song before it timed me out. After playing for just a few minutes, my fingers were burning. I took a picture so you can see the indentations from the strings that come from playing chords. I hope I get good and calloused soon so I can get through more than 5 minutes!
