This sound is taken from the Soviet national anthem, the anthem of the Soviet Union, which was introduced in 1944. Online, short excerpts became a long-running meme used in montage videos, country jokes and exaggerated patriotic edits. Its lasting appeal comes from how instantly recognizable and overwhelmingly grand it sounds, even in a very short clip. That contrast makes it useful for ironic comedy: a tiny action suddenly feels historic, triumphant or ominously serious as soon as the music starts.
