Place it as the payoff at the end of a defeat or farewell scene, after the build-up has landed. Follow it with clapping for the crowd reaction, then let hallelujah close the moment on a bigger finish. Keep it as the final beat, not the opening.

This clip is the bright, high-pitched chorus singing 'ding dong, the witch is dead' over a jaunty, old-fashioned tune, lasting just under thirty seconds. It feels gleeful and triumphant, like a whole town bursting into celebration at once. It comes from The Wizard of Oz, where the Munchkins sing it after Dorothy's house lands on the Wicked Witch of the East.
