<p>The Orchestra and Symphony Bands are definitely open to non-majors. I’ve heard both of them play and they’re pretty good (to my ear that quit all music after I graduated high school)</p>
<p>The one thing to keep in mind is that they practice three times a week for a pretty significant chunk of time in the afternoon. If you’re a science major, this makes scheduling labs difficult sometimes (but not impossible, I have a friend who has managed to juggle the two for several semesters but I believe its taken some careful planning on his part)</p>
