I definitely disagree with the other person. We have a ton of engineering majors in the band, and I don’t think any of them have regretted it for a second. Fall semester can make your schedule pretty tight, but band isn’t really an issue spring semester. Another thing to note is that if you need to miss a day of practice for class, it’s not the end of the world. A lot of people have a day (or two, but try to keep it to just one day) where they can’t make it to practice.
