Use it as the opening beat of a storytime edit, then follow the explanation with the Law & Order Dun Dun for a dramatic reveal, or finish an absurd twist with the DJ Airhorn Sound Effect.
About this sound
The short Portuguese cue, about eight seconds long, pairs a playful spoken announcement with a brief musical flourish to tell listeners a story is about to begin. It feels light and teasing, building anticipation for an explanation that may be dramatic, absurd, or far longer than expected. It comes from a recurring storytelling segment on Rá-Tim-Bum, the Brazilian children's programme that premiered on TV Cultura in 1990.
