I'm very sorry I don't speak Japanese. But I caught on to Yui's Solo very quick as I knew a good amount of the chords going in. My main obstacle was barre chords as most of them are very very difficult and uncomfortable to interchange and pose quickly on the fly. I eventually started practicing barre chords as well, at the risk of hurting my index finger (It still hurts when I try to do it) But needless to say. This was something on my mind I thought would be cool to play at like, a campfire hangout or something as it looks fun to jam to. I love this show :)
