Tightrope walking, also called funambulism, is the art of walking along a thin wire orrope, usually at a great height. One or more artists perform in front of an audience.

Tightwire is the art of maintaining balance while walking along a tensioned wire between two points.

Highwire is the same as tight wire but at much greater height.

Slackwire is when the tension on the wire is mainly provided by the load, i.e. the performer and props.

Slacklining is a balance sport which utilizes nylon webbing stretched tight between two anchor points.
