Losing horns

The unwanted sound heard on a game show, usually when a bonus round is lost.

On The Price Is Right, when a player loses his or her pricing game, or if there is a double overbid in the Showcase, these are signified by a tuba playing the first four notes of theme music followed by horns playing notes in C, D, and E all at once before pretending to faint. When Drew Carey hosted the show in 2007, an A-sharp note was added with faintly audible drums with the sound remixed in full stereo.

When you hear the losing horns on a game show, you know something went horribly wrong.

Tenor Horn

A awsome instrument far better than others like its friends the baritone or cornet. Tenor horn players are usually the best musicians of all time. And they well eventually take over the world.
