Guess the Melody is the Russian version of the international Name That Tune format, in which contestants compete to identify songs from only a few notes. The buzzer is central to that format, because pressing it first decides who gets to give the correct answer, so the sound has become shorthand for a confident guess. Short clips of the button have circulated online as a standalone effect, picked up by quiz makers, streamers and meme editors who want an instant game-show signal without using a full theme or a long musical excerpt.
