Zelda's Lullaby is the recurring theme of Princess Zelda in Nintendo's The Legend of Zelda series, composed by Koji Kondo. It became widely recognised after The Legend of Zelda: Ocarina of Time in 1998, where Link learns the song from Zelda and uses it throughout his journey. The melody has returned in later games and fan arrangements, especially gentle music-box and piano covers shared online. Its simple, lullaby-like shape makes it easy to recognise, hum and reuse, which is why it remains a popular choice for nostalgic, relaxing and sleep-themed content decades later.
