By now everyone, including those on quarter systems, should be back to school. Whether you're a senior realizing you'll need to face the real world soon or a freshmen figuring out how this whole college things work, it is never too late to get a head start on your career.
There is most likely some organization on your campus somehow related to music that can help you gain some sort of experience and meet other people into music. Of course, most places have a choir or band and a lot of schools have radio stations. Otherwise though, it may take some creative thinking. Your school's newspaper probably has an entertainment section. The television station could lead to some experience in film, great if you'd like to work in publishing. Maybe the theatre group needs someone to run lights and sound, great experience for working in venues.
Check the Course Catalog
Even if you go to the smallest college in the middle of nowhere it's fairly likely your school has at least a few classes related to your future career in the music industry. Intellectual property law is essentially to understanding the industry. Most schools have business classes and these can certainly help. How about public relations? Music theory or history? Even psychology and sociology can help you better understand the fans of bands you might work with.
Look Around Campus
Both on and off campus, there are plenty of opportunities to get involved in the music scene. Does your school hold yearly concerts? Find out who is charge and how you can get involved? If not, how about a local venue? Volunteering is a great way to get your foot in the door anywhere. If your school or town really doesn't have what you're looking for, why not start something new?
Best of luck, have a great year, and be sure to share your ideas in the comments!
