 It is important to note that not only the fingers are involved in the plucking of the string, but the hand should also be held comfortably loose and may move slightly as well - even the arm is involved.For example, when playing scales (usually with alternating fingers, e.g., index, middle, index, middle, ...) and moving from the top strings down, or the bottom strings up, the hand moves up and down as well in order to adjust the placement of the fingers to be at an optimum.Tirando (also known as free-stroke) is where the plucking motion is made in such a manner that, after plucking, the finger stays in the air - it does therefore not land on an adjacent string.
