This will be the first post of a small series, focusing on the history, development and performance of the original Koryo form. I will refer to this as "Koryo Hyung" for the remainder of this series to not confuse readers with the normal, mainstream, "new" Koryo Poomsae which most practise today. So when I write "Koryo Hyung" that is the old one, and Koryo Poomsae is the current one.
As a Taekwondo Nerd I have always read a lot of Taekwondo history, and one thing caught my interest many many years ago was a reference that looked almost the same in all articles and books on modern Taekwondo history. Especially if the book or article touched upon the development of the Korean Taekwondo Association forms (the Poomsae we practise today). It was something along these lines: "Around 1965-67 a committee consisting of representatives from most major Kwan (schools) developed the Palgwae and Judanja (Black belt) Poomsae. In 1967-1972 the same committee with the addition of representatives from Ji Do Kwan and Mu Duk Kwan developed a new series of forms. In 1972 the Palgwae and Koryo were replaced by the new forms, the Taegeuk series and a new Koryo form." This or a close variation of this quote appeared everywhere and it bugged me to no end. You see the Palgwae were replaced but they did live on. I could find videos, books, articles, webpages with detailed descriptions of them with no problem. A few of the books in my Martial Arts library were bought precisely because of my interest in what these forms were like. Not so with the original Koryo.
