 And Earl Scruggs came up with this idea. I was having dinner with him and his son Gary, and we were talking about dreams, and Gary said, Earl, tell Tony how you came up with this idea of detuning your banjo. And Earl said, well, I dreamt it. He had this dream of detuning his banjo. We have these special things that allow us to do it perfectly every time. But when Earl first recorded it, he did it. He just did it by ear.
