Tightrope walking (or funambulism) is the art of walking along a thin wire or rope, usually at a great height. One or more artists performs in front of an audience.

• Tightwire is the art of maintaining balance while walking along a tensioned wire between two points. It can be done either using a balancing tool (umbrella, fan, balance pole, etc.) or "freehand", using only one's body to maintain balance. Typically, tightwire performances will fall into one of two distinct types of acts: dance/movement or object manipulation. It is common for tightwire artists to include a variety of props in their acts, such as clubs or rings, hats or canes in order to help them maintain their balance. Other artists will take props onto the wire in order to enhance the entertainment value. These often include juggling clubs, spinning plates, wheelbarrows with passengers, ladders, pets and children.
• Highwire is the same as tight wire but at much greater height. Although there is no official height when tight wire becomes high wire, generally a wire over twenty feet high will be regarded as a high wire act. Traditionally, the difference is in style of performance.
  
• Slackwire is when the tension on the wire is only provided by the load, i.e. the performer and props. The difference is that to balance on a tight wire the performer must keep his centre of mass above his feet, while on a slack wire he moves the wire with his balance to under his centre of mass.
• Skywalk is a form somewhat akin to highwire, but generally defined by its length and height, often taking place outdoors at great heights, often between skyscrapers, gorges, mountains or other natural and man-made landscapes.
• Slacklining is a balance sport which utilizes nylon webbing stretched tight between two anchor points. Slacklining is distinct from tightrope walking in that the line is not held rigidly taut; it is instead dynamic, stretching and bouncing like a long and narrow trampoline.
• Freestyle slacklining (a.k.a. “rodeo slacklining") is the art and practice of cultivating balance on a piece of rope or webbing draped slack between two anchor points, typically about 15 to long and a couple feet off the ground in the centre. This type of slackline provides a wide array of opportunities for both swinging and static maneuvers. A freestyle slackline has no tension in it, while both traditional slacklines and tightropes are tensioned. The slackness in the rope or webbing allows it to swing at large amplitudes and adds a different dynamic to the art.

Nuorallakävely eli nuorallatanssi on tasapainotaitelua ja akrobatian harjoittamista korkealle pingotetulla vaijerilla tai köydellä. Nuorallatanssijat esiintyvät tavallisesti sirkuksissa tai muunkaltaisissa järjestetyissä näytöksissä.
