The Alphabetic Dance Notation Information Administration of Korea has developed the program Ryultong .

The program consists of dance score editor, dance simulation, dance notation input and dance notation education. It makes it possible to write, edit and print dance score, and is fused with graphics, inverse kinematics, regeneration of video based on human motion characteristics and physical simulation technology to show the idea of choreographer in three dimensions.

Besides, it has systematized and simplified the notation in conformity with the principle of dance movements, so that the notation can be used in an easier way and the dance score reproduced in a realistic way on the computer.

“Frankly speaking, the course of creating a dance includes tens, sometimes hundreds of modifications. However, Ryultong helps a choreographer improve the level of depiction and save much labour and time in creation as he or she can modify and complete the work by using a virtual actor on the computer,” says Ri Yong Chol, choreographer at the Phibada Opera Troupe.

“Generally, teachers give students the idea of dance movements through demonstration, the first stage of practical dance education. But it was difficult to ensure the accuracy of the movements of hands and bodies at a high level as the dance movements were different from one teacher to another. But the program is useful in making students understand standardized dance movements and ensuring the accuracy of their performance,” says Chae Hyang Sim, teacher at Pyongyang Kim Won Gyun University of Music and Dance.

Putting the Korean alphabetic dance notation on a scientific and IT basis is associated with the exploits of the peerlessly great men, who worked heart and soul for the development of the Korean-style dance notation, foreseeing the importance of the dance notation in developing the art of dance scientifically.

Thanks to the initiative and meticulous guidance of Chairman Kim Jong Il , the research for developing the Korean-style dance notation began in the early 1970s, and it was created in the mid-1980s.

He gave instructions on further perfecting the notation. One November day in Juche 99 (2010), he gave on-site guidance at the then Pyongyang University of Dance and set forth a task of developing a program for dance score. This is the origin of the introduction of the programming of dance notation.

On July 20, Juche 105 (2016) and on several other occasions, the respected Comrade Kim Jong Un set forth an important task of putting the Korean alphabetic dance notation on a high scientific and IT basis. In October 2019, he reinforced the research team with competent scientists and technicians and gave instructions regarding their work.

Based on the successes and experience gained in the alphabetic dance notation research, the research team developed Ryultong by optimizing the notations and their combination method, thus contributing to visualizing dance score and movements, writing dance score, inputting dance characters and educating in dance notations.

At present, preparations for introducing the system into the sector of the art of dance are going on at the final stage.
