This is how Donald Trump engineers applause.

16. claque

Trump is actually reviving a very old tradition — the tradition of the claque. A claque is a group of people whose job is to generate applause. In the description of the 1911 Encyclopedia Britannica, a claque is:

an organized body of professional applauders in the French theatres. The hiring of persons to applaud dramatic performances was common in classical times, and the emperor Nero, when he acted, had his performance greeted by an encomium chanted by five thousand of his soldiers. … The recollection of this gave the 16th-century French poet, Jean Daurat, an idea which has developed into the modern claque. … There are commissaires, those who learn the piece by heart, and call the attention of their neighbours to its good points between the acts. The rieurs are those who laugh loudly at the jokes. The pleureurs, generally women, feign tears, by holding their handerkerchiefs to their eyes. The chatouilleurs keep the audience in in a good humour, while the bisseurs simply clap their hands and cry bis! bis! to secure encores.
