So you playing this four for volume. Then you play them middle four. If you're going to play a single string, you play these small strings. That's the E, B, G, D. You play them four. That's where most of them solo guitars plays on, this little E, because it's high. You see them rock-and-roll, heavy metal. They get way up the neck. Sound like a clarinet up there, or a flute, piccolo. That's it. They want something solid, they get here. They want something heavy, rhythm, you play here. So that's three elements of what you got. You master that. You ain't going to get none of them virtuosos to be fooling with these others four, sets of four.
