“ZITHER (Endangered)”: The 13th completed molecule of the upper grid of the Score Movie for my opera entitled “Endangered Languages, Endangered Cultures, Endangered Ideas” out of a projected group of 15. Each Roman Numeral represents an instruction for the players who move across a grid that corresponds to the maximum grid of the movie. “Endangered Languages..” is an ecosystem that participants within can’t control but can try to influence. The hypothetical objective is to keep biolingual diversity alive & to resist homogenization of the world by maintaining a healthy complexity. - December 19, 2016 E.V. notes from tENTATIVELY, a cONVENIENCE
