That's wota art called MIX! MIX(ミックス) is a very special class group, which needs a certain number of people to get together. 1. The method is in the prelude or interlude of the song. First, a person takes the lead in shouting "よっしゃくぜー!" Then a group of people formed a circle and shouted the following slogan: タィガー! ファイヤー! サイバー! ファイバー! ダイバー! バイバー! ジャージャー! (Tiger! Fuoco! Cyber! Fiber! Divers! Vivo. Jaya! Tiger~viver is a bar, then stop a bar and shout JaJa, a total of eight bars, and then the song begins. In other words, you must start shouting correctly before the eight bars of the song, so there are not so many songs to play. 2. Popularizing "ミッス" is more common in AKB48 and seiyuu activities. Good morning family concert, almost no one played "ミックス". But at present, at least there are a few people playing "ミッボス" in Ute and ポシボス. For many long-term teachers, in short, it is very noisy. This is an annoying point. 4.MIX comes from a poem: a tiger is like a fire, like a human being, made by people, refined, new and new. Man-made, fiber, sea girl (a diving girl who catches shrimp), vibration and chemical fiber flying off are translated into Tora, Hi, Zou Jin, Seni, Ama, Shindou and Carson -tobi-Jokyo respectively. However, the origin of this poem is unknown. 5.AKB48 MIX (used for AKB48 concert): fire segment ヲタィガーァィヤーサィ. Fire (hey)! Artificial (Zou Jin)! Sen me! Sea girl (grandmother)! New bucket! Carson! Fly (to finish) and move (jyo-kyo)! The second time is the third paragraph ヲタチャペ, ァペ, カラ, キナラト. ミョーホントスケ Chia is a Beka Ra Ke Na Ra Tou Su Ke Miyo-Hontou Su Ke is the third time in the final.
