The Flintstones is the classic American animated sitcom created by Hanna-Barbera that debuted in 1960, and its opening theme, Meet the Flintstones, remains one of the most recognisable cartoon melodies ever written. Short recorder renditions of the theme have become a small internet staple: the recorder, called flauta doce in Portuguese, is a school music-class instrument in Brazil, so its breathy sound carries a strong nostalgic pull. Stripped-down covers like this one circulate as memes, WhatsApp audios and reaction clips, working as a quick retro punchline.
