Well, ok. I'm friends with these two girls, and I became friends with one of their friends -- a guitarist. He's in grade 11 and plays acoustic guitar. We talked about music for a while and a few days later, I actually saw him play something. He used his index finger whenever possible, and attempted hammer-ons by lifting his index off of the fret he was on and then hammering the other fret with his index finger. Deciding to inquire if he'd learned any scales (these usually teach musicians to use all their fingers), he said no. Shocked, I told him that learning scales is the first thing all fledging guitarists should do. He says "No, I have a poster on my wall with all of the chords on it". I try to explain to him what I meant, but he insists that because of the poster, he doesn't need to learn scales. I was talking one of my friends that knows this guy, and I was told that the guy had been playing for over 2 years .
