Sencha is one of the default alarm tones Apple included with iOS for iPhone, named after Japanese green tea alongside other calm, nature-inspired tones. While many users know it simply as their weekday wake-up sound, the recording spread online as a recognisable shorthand for phone alarms in edits, skits and memes. Its looping marimba pattern became familiar enough that creators can drop in just the opening notes and audiences immediately understand a morning scene is starting, even without showing a phone or clock on screen.
