Long ago, when kings, queens and emperors ruled many nations, they often had a system whereby others would announce their arrival in an impressive way. Especially when there was a large crowd of people talkingand making noise, one very effective way to get their attention and make them stop talking was to have one or more musicians blow (or "toot," which is a more childish term) upon a horn.
