"Invented by. . . ?"

I saw Carlos Montoya doing that as a variation in a flamenco solo in a concert back in the early 1960s. It's one of a large number of techniques that flamenco guitarists toss in from time to time, but they don't base whole pieces on it. Used sparingly, it's pretty impressive. Used for a whole piece and it begins to show its limitations.
