Everyone looooves hearing the theme to Harry Potter, Star Wars, Jurassic Park, musicals, disney music, and much more. This music doesn't necessarily have any words, but for some reason, the general public loves hearing film scores.
Film scores are classical music, whether people like it or not. Big time composers such as John Williams and Hans Zimmer devote their lives into creating beautiful film scores.
So why is it that people love hearing these scores, but dislike hearing scores that are not in movies? I think it has to lie around peoples memories with the music. People love hearing these film scores because they have positive memories and nostalgia connected with them. Therefore, people like some classical music songs.
It's totally possible to like more of the classical genre too! All that's necessary is to create a positive listening environment to promote good memories.
Another thing many people won't realize is that these common movie music themes sound very familiar to classical songs that have already been written. See? Without even realizing it, you actually do enjoy some classical.
Here's a picture of John Williams, the man behind the music of Star Wars, Jurassic Park, Harry Potter, and much more.
