The sad trombone is a long-running comedy cue from vaudeville, radio and early cartoons, built around a muted trombone sliding down in four descending wah notes. It became a television shorthand for losing and embarrassment and later spread online as a downloadable fail effect for videos, streams and soundboards. The Portuguese word triste in this version points to its wide use in Brazil and other Portuguese speaking communities, where creators use the same cue for mistakes, bad news and anticlimactic endings.
