Are Minors Helpful?

Question from Candidate:
I am very lost. How exactly do minors work? I know they are an opportunity for you to learn more about something different than a major, but do you get a degree in your minor also? Does your minor show up anywhere like on your degree or would your official title be John Doe degree in Business and minor in Art? How do employers look at minors?
I’m thinking about getting a major in sociology and a minor in music. How does that sound? Is it useless to have your major and minor in two separate topics? I mean what does your minor really do?
