If you’re a “Harry Potter” fan, which if you were born after 1990, you probably are, you’ve likely found yourself singing along to the score while watching the movie. The music is already a big focus of the films, and if you attend a Louisville Orchestra live scoring of one, it turns up the spotlight on the instrumentals by 1,000 Lumos incantations. The band will play along to the fourth film, “The Goblet of Fire,” as its projected behind them in high definition on a large screen. A magical evening to be sure. —Danielle Grady
