I hope your search for engineering schools is coming along well! My first suggestion when looking for engineering schools is to confirm music and foreign language courses are offered. I believe that wont be hard to find as many schools consider foreign language and exploratory classes like music to be part of the core curriculum. If you are interested in learning if engineering is for you, you could explore engineering during your freshmen year. In a typical semester with 5-6 courses, half can be allotted to engineering and the other half towards other studies. After completing various studies within freshmen and sophomore years you will have a better understanding of engineering and can better determine if you would like to advance in that field and pursue mastery courses. There is plenty of time to sort it out and many resources to rely on. I recommend getting to know your professors from the engineering, foreign language, and music departments. By explaining your interests, you professors may be able to guide you towards exploratory programs and experiences. When attending my undergrad, I learned more about engineering by attending a presentation at my university. It was pretty cool hearing from innovative engineers visiting all the way from Seoul, Korea.
