This is the Emishi flute from Negishi Shinobue Workshop. This type does not have a mouthpiece directly below the node. It is recommended for those who are bothered by the node and find it difficult to play. This flute's hertz is adjusted to match current music (441-443Hz at 20°C). This flute is an ancient flute from the Tohoku region. It is believed to have been used by the Emishi people in rituals such as burying and memorializing the dead. It is also thought to have been used to encourage those suffering from the loss of a loved one or illness. (There are many tales and legends about the Emishi people in the Tohoku region.) It is also said to be the flute used by Minamoto no Yoshitsune in his childhood (Ushiwakamaru). It is believed to have been introduced from South America, but the details are unknown. The bamboo nodes are formed according to the purpose. (Natural law) In the case of the Emishi flute, if certain conditions are met, regardless of the thickness, hardness, or length, the mouthpiece is opened just below the node, and finger holes are opened between the nodes, and when the tube itself is slowly sounded without blowing at 15°C, it is tuned to 440-448Hz G pipe (standard Do-Re-Mi scale, six holes, three-hole tuning). (The hertz is slightly higher than current music.) From the Meiji era to the beginning of the Showa era, small elementary schools in mountain villages did not have organs. The Emishi flute was played to teach children nursery rhymes and folk songs of the land, and the children were delighted. I have heard stories from people who actually sang nursery rhymes with the Emishi flute. It's very fun, and it makes me cry when I remember it. They said the Emishi flute was easy to sing with. I have been researching physics using the laws of nature for many years and can identify bamboo that meets the conditions. After the Great East Japan Earthquake of 3.11, this flute was revived to commemorate the deceased and to encourage those who are suffering. Many festival flutes in the Tohoku region are based on the Emishi flute for hayashi and kagura (Akita Kanto Festival, Morioka Sansa Odori, hayashi and kagura in the inland areas of Akita, Iwate, and Yamagata prefectures, kagura on the coast of Iwate Prefecture, etc.). Thickness: Approximately 25.1 mm at the mouthpiece Length: Approximately 43.7 cm Mouthpiece size: Approximately 13.5 mm Bamboo hardness: Normal Thickness: Normal Range: From the fundamental tone to the high tone 6 (a fingering chart is available) Because natural materials are used and it is handmade, there may be variations in color, shape, bending, and scratches.
