I’m moving into my dorm in a week and I was curious what I should bring as a vocal performance major? Ex. Humidifier, meds, tea, etc. I’m 18 and a soprano if that means anything 
also I live in wisconsin so winter exists
Hi meetmeinopera. How exciting! Your biggest threat will be getting sick. Did you get a flu shot yet? Do everything you can to stay rested, eat healthy and practice good hygiene. Humidifier is good but also a nettie pot or other sinus rinse to keep nasal pasages clear is pretty standard, but just use plain water. DD also likes her Britta water bottle. Having enough water is important so she always has a water bottle with her. Have hand sanitizer and cleaning supplies to keep your room clean. You may need eye mask and ear plugs for sleeping if you have trouble going to sleep when a roommate is up. Getting enough sleep will be important. DD does have some favorite teas and throat treatments but I think they vary.
Humidifier is good. Dorm heat is dry.
My D liked a personal steamer - good for the voice and skin. S’s favorite accessories are a water bottle and an assortment of scarves (he swears that keeping his neck warm improves his voice.) Oh, and figure out an efficient and convenient way to store/organize all of your sheet music - you will end up with enormous piles of paper.
