Place it after the dialogue ends and before the closing visual, where a pause in the action is needed. Follow it with a soft page-turn or distant rain effect to close the sequence, or precede it with a single door-close effect to mark the departure.

This 18-second clip is the opening of Sadness and Sorrow, an instrumental piano and flute theme with soft strings underneath and no vocals at all. It feels lonely yet warm, heavy with grief and quiet remembrance rather than shock. Toshio Masuda composed it for the original Naruto anime, and it became closely linked to loss, exile and childhood flashbacks.
