Place this clip at the top of a school scene, right before dialogue starts, then follow the lesson moment with an anime wow sound effect for a reaction beat and save the bell ding sound effect for a single correct answer later.
About this sound
This clip is a melodic school chime lasting about twelve seconds, played as a clean sequence of bell tones rather than a harsh alarm. It feels orderly, calm and a little nostalgic, instantly putting a listener in a school day mindset. The melody is the bell used in Japanese schools to signal the start and end of class.
