Above is a video of tea master Kim Myung Soo teaching the Korean powdered tea ceremony to Pedro. One studied extensively under Kim Myung Soo and directed Pedro to her on his second trip to Korea. He did pretty good as this is his first time learning the ceremony. This is how the tea ceremony is often taught to individuals, they are placed facing the teacher and just continue to go through the motions until the routine is put to memory. It is refined a bit and individual differences or very slight modifications are tolerated.
You will instantly notice upon watching the video that this tea ceremony is quite different than the Korean powdered tea ceremony video of Hong Kyeong Hee. This is completely normal and accepted in Korea as the powdered tea ceremony has no strict prescribed pattern that has been passed down. Rather basic principles are followed and naturalness is most prized. Of note is that both Hong Kyeong Hee and Kim Myung Soo's ceremonies are almost exactly 10 minutes long.
In Hong Kyeong Hee's ceremony he is just a little bit unnatural and robotic in this movements at the beginning of his performance. This could just be from nerves as he settles into more natural movements and pace as the tea ceremony progresses. Sometimes his tea ceremony feels as thought it lacks some natural feeling with the pauses being too poignant and slightly overdone with not enough fluidity between actions. Nonetheless, it is a great powdered tea ceremony.
Kim Myung Soo's ceremony has much more of a natural flow. Her movements are relaxed, unpretentious, and have a nice continuity to them. They seem a bit more genuine. Of course this may have a bit to do with the fact that she is not preforming this ceremony in a foreign country in front of an audience.
What is most important is the lesson that Kim Myong Soo expounds at the end of the video. She reveals that the true core of all Korean tea ceremonies has less to do with timing, pace, and movements and more to do with the sincerity of the connection between the heart and mind of the host and guest. The tea and the ceremony surrounding it acts as a conduit to strengthen this bond.
