The ringmaster called the audience's attention as the acrobats prepared for their performance.
Ringmaster → It is formed from "ring" (from Old English "hring", meaning a circular band or circle) and "master" (from Old English "maegester", meaning one who has control or authority). The word "ringmaster" refers to a person who has authority or control over a performance in a circular arena, such as a circus.
Think of a 'circular band' ('ring') where someone is in charge ('master') — that's why a ringmaster is the one who leads the show in a circus.
