The melody is Marimba, the default ringtone of the first iPhone released in 2007, and its short looping notes became one of the most recognised phone sounds in the world. Clips using it spread across YouTube, TikTok and WhatsApp as creators recreated incoming call moments, phone pranks and interruptions without using a real phone. It remains popular because audiences identify it in a second, much like a discord call ringing, and instantly understand that someone is trying to reach the character on screen right now.
