 Artificial harmonics are played by stopping the string as usual with the left hand then resting (not pressing) the index finger of the right hand on the string at a nodal position (commonly 5, 7, 9, or 12 frets above the left hand finger) and plucking the string with the ring finger or thumb of the right hand.In the left hand, each finger is responsible for exactly one fret.For each hand-position of four frets, the left hand is stationary while its fingers move.
