The original Zelda game featured three melodies that would come to define the franchise: the Secret Unlocked Sound, the Treasure Chest sound, and the classic Zelda theme. Throughout the series, these melodies have been transformed again and again. Each version reflects the hardware it was made for, and Nintendo’s evolving approach to these iconic games.

Music is a quintessential part of the Zelda series. And some of Zelda’s most iconic melodies go all the way back to the original game, on the Nintendo Entertainment System. These tunes were born in an age of 8 bits, and 5 lo-fi channels of audio. But those limitations forced composer Koji Kondo to make them as distilled and powerful as possible.

The history of recorded sound stretches back over a hundred and fifty years, starting with a device that could “record” a voice on a piece of paper. Today, we can enjoy lossless streaming anywhere we go… but getting here wasn’t easy. In this episode, we worked with Qobuz, the high quality music platform, to chart the history of audio mediums, from cylinders made of tin foil and wax, to vinyl, 8-track, cassette, CDs, and mp3s. Along the way, we explore the innovations and quirks of each format, with memories sent in from our listeners and the 20K team.

Baseball fan or not, there’s one song that virtually every American knows… or at least, we think we do. “Take Me Out to the Ball Game” is one of the top three most recognizable songs in the country, next to “The Star Spangled Banner'' and “Happy Birthday.” But if you dig into the lyrics, you’ll find a forgotten message buried among the peanuts and Cracker Jack.

Our vocal system is incredibly complex. What we call “the voice” starts with very precise movements of our vocal cords, and then goes through an entire “resonation system” that includes our throat, mouth, lips, tongue, and teeth. With enough control over these components, people can do some truly mind-bending things with their voices, creating sounds that feel out of this world—from rumbling lows to piercing highs, and even two notes sung at once.

Why do bugs make the sounds they do? And how do they make them? In this episode, we explore the un-bee-lievable world of insect sounds, including crickets who craft tools to make themselves louder, and moths who can jam the natural sonar of bats. By the time it’s over, you’ll never hear these buzzes and chirps the same way again.

In honor of Mental Health Awareness month, we’ve revamped one of the most personal episodes we’ve ever worked on. To create it, Dallas worked with the team from Meditative Story to tell a story from his former life as a musician. It’s about losing the thing that had defined his life for more than a decade, and finding something entirely different in the process. This remix concludes with an all-new segment where Dallas reflects on what it was like to finally share this story.Check out our new store at 20k.org/shop.Watch our video shorts on Youtube, Instagram, and TikTok.Follow us on Reddit, Twitter, and Facebook.Sign up for Twenty Thousand Hertz+ to get our entire catalog ad-free.If you know what this week's mystery sound is, tell us at mystery.20k.orgGo to indeed.com/hertz to start hiring today.Find the right doctor, right now with at zocdoc.com/20k.Subscribe to Meditative Story wherever you get your podcasts.Episode transcript, music, and credits can be found here: https://www.20k.org/episodes/breathedeep Learn more about your ad choices.

 In the 1960s, stereo sound revolutionized the music industry. But it turns out, a pioneering engineer named Alan Blumlein had actually invented stereo a full three decades earlier. Due to tragic events in World War II, his innovations were forgotten for decades. In this episode, we worked with OnePlus to tell the story of how audio has evolved from mono, to stereo, to quadraphonic, to surround sound and beyond. Today, we even have immersive, three-dimensional systems that can simulate 128 speakers using just two.

Have you ever seen something so cute that you just wanted to squeeze it? Have you ever felt sleepy after a big meal? Or enjoyed bouncing on a puffy cushion? There are words for all of these, just not in English.
