Flauta doce is the Portuguese name for the recorder, a woodwind instrument widely taught in schools in Brazil and Portugal because it is simple and inexpensive to learn. Short recorder clips circulate online as sound effects because the breathy tone is instantly recognisable, even to listeners who never played one. This effect has been shared in that soundboard format, used less as a musical performance and more as a comic or sentimental cue that viewers understand within the first few notes of the phrase.
