I have a question about TKD patterns. They seem to come from several different sources and have several different sets of names, as TKD was created during the 1950s; some of them from shotokan karate, but some came from elsewhere. The geneology of TKD patterns makes karate look positively straightforward.
There's 3 different sets as far as I can see, the karate based ones (Pinans and Passai), the ITF based ones and the WTF ones. Then there are the local origin martial arts from which TKD originated;ssireum (sumo), subak and taekkyon and the chinese influence with gwonbeop.
Now the karate influence is pretty clear with the pinan katas and it seems that qwonbeop is basically quan-fa so I'd have thought it likely theres some forms from there. Clearly some of the other patterns are based on pinans but re-arranged almost randomly as far as I can tell.
Frankly it's fairly confusing. Wouldn't there have been some pre-1950s forms which haven't been modified heavily which made up the original martial arts? What's happened to them?
