Amara (from Mongolia) and I went to Mongolian concert in Tottori. Mongolian throat singing is known as Khumii and of my interest. I have been practicing the Khumii in labs for a long time. Sound frequency of turbo pump is similar to that of Khumii sounds.
After the concert, I demonstrated my Khumii to the main singer and he told me (Amara translated) that I already passed novice-player step and need proper exercise to go next.
Chinggis Khan praise, Four season steppe, Milk god, and Altain mountain praise were pretty good.
