The classic alarm is one of the default alarm tones built into the iPhone, familiar to millions of people who have used an Apple phone as their morning alarm. Because it shipped on the device itself, it became instantly recognisable without ever being released as a song or promoted separately. Online, creators reuse the tone in videos about waking up, being late, and phone addiction, where the sound alone tells the audience what is happening. Its continued use comes from that shared recognition, as almost anyone who has owned an iPhone knows the feeling of hearing it in the morning.
