Imagine how an invented North Pole music department could organize composition, recording, archiving, rehearsals, and seasonal programming.
Use Santa and the North Pole as an explicitly fictional creative setting. The goal is to turn imaginative details into useful ideas about music, storytelling, organization, or sound.
Turn the fictional premise into a creative brief. List the setting, audience, recurring motif, key sound or event, and the single detail that makes the concept recognizable.
