does your school allow people from different departments to live in the same dormitory? If possible, I suggest that you work with different departments, which can really broaden your knowledge. Although you may be a little uncomfortable in life at first, it will be very interesting after a long time, and if you practice music, you will rarely do it in the dormitory. Even if all the people in your dormitory are engaged in music, the dormitory next door may be noisy by you, so as far as practice is concerned, you usually don't do it in the dormitory and often go to the rooftop or a special place, so it is really unnecessary to deliberately arrange the dormitory unless there is a special guy in your dormitory.
