Parents fed up with the soundtrack of "Frozen," which seems to be stuck on repeat in their children's brains, might also not want to hear this advice from a music professor at Northwestern University, who regularly deals with unrelenting melodies.
"Leave it there, and enjoy it," said Ryan Nelson, music director in residence for Northwestern's School of Communication. "With everything, popularity always wanes and something always replaces it."
The tip might be too little, too late, however, for "Frozen"-fatigued parents who have taken to social media and parenting blogs to rant about the pervasiveness of the music from Disney's highest-grossing animated movie.
"For weeks, we've had to look at the girls and say, 'Girls, we need to perform, not sing the song,' " said Kristen Ramirez, owner of Baby Take a Bow dance studios in Roscoe Village and Winnetka, Ill., where she added a fourth "Frozen" summer camp over the weekend to accommodate the demand. "The music does take over."
The staying power of songs such as "Let it Go," performed by the character named Elsa in the movie, can be attributed to a quality that musicians call the "hook," said Nelson, who oversees music theater productions at the university.
"It's a part of a song that keeps coming back that really gets you," he said. "It's not just the melody, or the tune. It's also the text and the lyrics."
Katherine McHenry, owner of Building Blocks toy stores in Lakeview and Wicker Park, Ill., said the movie's popularity is still so strong that she had no hesitations about ordering $10,000 in "Frozen" merchandise, for which she's allowing customers to pre-order. Minutes after sending word of the incoming goods through e-mail, McHenry started receiving phone calls and Internet orders, she said.
"I have a whole community of moms in my personal life, and also my customers, who are like, 'We've watched "Frozen" four times today,' " she said.
