You can’t tell any kind of a story without having some kind of a theme, something to say between the lines. – Robert Wise
Inspired by Song
Find a song with a narrative. Shoot visuals to tell the narrative in the pace of the song. No lip sync, no dance, it’s not a music video. You should be able to tell the story with the music off.
Or, take the narrative from the song and write a script based on that narrative.
