Rasgueado

Rasgueado (also called Rageo (spelled so or Rajeo), Rasgueo or Rasgeo in Andalusian dialect and flamenco jargon, or even occasionally Rasqueado) is a guitar finger strumming technique commonly associated with flamenco guitar music. It is also used in classical and other fingerstyle guitar picking techniques. The rasgueado is executed using the fingers of the strumming hand in rhythmically precise, and often rapid, strumming patterns. The important characteristic of this strumming style is the fingernail (outer) side of the finger tips (as opposed to their fleshy inner side) is also used, and in such case, in reverse of the way it is done when the fleshy side of the finger tips is used, namely downward (index, middle, ring and little finger) and upward (thumb).
