Tapping is a guitar playing technique, where a string is fretted and set into vibration as part of a single motion of being pushed onto the fretboard, as opposed to the standard technique being fretted with one hand and picked with the other. It is similar to the technique of hammer-ons and pull-offs, but used in an extended way compared to them: hammer-ons would be performed by only the fretting hand, and in conjunction with conventionally picked notes; whereas tapping passages involve both hands and consist of only tapped, hammered and pulled notes. Some players (such as Stanley Jordan) use exclusively tapping, and it is standard on some instruments, such as the Chapman Stick.
