Twenty Thousand Hertz

David Jeffers has always understood the world through sound. As a kid, he bounced beats between tape decks and built speaker boxes from spare parts. After college, he founded an underground hip hop label. Then came the day that split his life in two. And in the quiet that followed, David started listening more deeply… and piece by piece, he built a new life, guided not by what he lost, but what he could create.

What does a time machine sound like? Or a magic carpet? For the BBC Radiophonic Workshop, that was just another day at the office. For 40 years, this oddball collective of engineers and composers pushed the boundaries of sound design, crafting eerie atmospheres, quirky jingles, and the iconic audio of Doctor Who. In this episode, we explore the rise and fall of this pioneering studio with composer and archivist Mark Ayres, and uncover how these sonic wizards shaped the future of sound.

The theme song to Reading Rainbow has been delighting kids (and nostalgic grown-ups) for over 40 years. But how did this instantly iconic track come to be? In this episode, composer Steve Horelick reveals the unlikely story of its creation, from its empowering lyrics, to its “fluttering butterfly” synth sound, to how Chaka Khan and a mystery drummer helped shape one of its later versions.

Every New Year’s at midnight, we raise our voices to sing a song that few of us understand: “Auld Lang Syne.” So when and why did this become the anthem of the holiday? In this episode, our friends at the Smithsonian’s Sidedoor podcast trace the mysterious rise of “Auld Lang Syne” from rural Scotland, to a New York jazz club, to a classic film and an iconic actor. Featuring folklorist Jim Deutsch.
