Whether you call them kata, taolu, or hyeong, forms are an interesting source of debate.
Watch a martial artist train and you may believe forms are only rehearsed tactics for self-defense.
Watch another martial artist and you may believe forms to just be an unusual dance, one that teaches coordination and the harmonies of the body.
Watch yet another martial artist and you may believe it is simply an exaggerated performance meant for the eyes (and ears) of tournament judges.
Spoiler alert: none of these are fully correct nor are they fully inaccurate.
