Opening sound
The first 200–500 ms of audio in a short-form video.
Opening sound is the audio equivalent of the first thumbnail frame. It triggers a scroll-stop decision before any visual content registers.
Trending sounds give an initial reach boost, but original sound design tends to perform better long-term.
Silence at the open is a documented retention killer on Shorts and TikTok.
