I play flute so just being a performance major doesn’t have great career prospects imo, but I’d really love to go to a school where double majoring or getting a double degree is possible. I’m thinking schools like Lawrence University, St Olaf, etc but I’m looking for more options preferably not in the Midwest. For a second (academic) major I’m undecided but thinking about neuroscience. I also need to get merit aid if the tuition is crazy, so schools like Oberlin just aren’t in the budget because I won’t get need based aid. My stats are 33 ACT, 3.98 gpa, National merit high scorer (probably going to end up commended but not semifinalist) and I have some music accomplishments ie all state orchestra and performed in a masterclass. If anyone has any advice about doing performance on a competitive instrument like flute, that would be welcomed too 
There is a long thread on this already. I tagged you so you can read as it is very informative and comprehensive.
There are countless threads over the years on this topic, each with its own twist
I think, first of all, that it might be helpful to read the Double Degree Dilemma essay by David Lane, closer to the top of the music forum. It is really about the different ways to study music.It uses individual students as examples and a lot of people find that approach helpful.
A double major in neuroscience and music might be pretty difficult, but is doable at a few schools where gen eds are few or not required. Both majors are intense, with labs for science and practice, rehearsals and performance for music. Both have a sequence of courses that are foundational. Both are very time consuming.
A double degree takes 5 years and that means paying for that extra year. But that makes the scheduling a little easier.
There are other viable options. You can major in neuroscience or anything else for a BA or BS and continue lessons and do performance as an extracurricular (and integrated into classes at some schools). Lessons are often funded by the school and often both lessons and performance are given credit. You could take theory and music history as electives.
You can also consider being 'just a performance major." Music majors can go on to many kinds of jobs, grad school and teaching, and professional schools like law or medicine (music majors have a high acceptance rate at med schools.)
A BM is 2/3-3/4 music classes and usually means audition for admission.
A BA in music is 1/4-/13 music classes and often means auditions in the fall for extracurricular ensemble. You would do a music supplement with recording, music resume and letters from teachers/director. A BA includes theory, music history, analysis, composition ethnomusicology and technology.
So…the options are BA or BS in area other than music (with music lessons and EC performance), BM , BS/BM or BA/BM, double major within a BA or BS, and double degree. You can also do a BA in music and take electives in science but that doesn’t seem like it would fit your goals.
For examples, look at Bard (I know someone who went there and did science but continued music and then got a PhD in music) and Lawrence (Lawrence gives merit). Clark University has a good music dept. and you could study science there (and they give merit). Vassar and Sarah Lawrence. College of Wooster. (Check out Colleges that Change Lives website). There are so many schools we could suggest once you are clearer on what you want.
The hard part here is the need for merit aid. That will take some research or others can make suggestions. It’s possible a state university would meet your needs. I would start with schools that might be affordable and then decide on what degree path you want and how you want to pursue music. And remember you can apply to several options and decide in late April of senior year.
Any chance you are doing a summer program? That can be very clarifying.
Maybe the University of Rochester. It has a separate Eastman school of music, offers neuroscience, and medical school on premises. See the accepted students threads there for an idea on expected merit aid given your stats.
For a reach you may want to look at schools like Duke and Notre Dame, where you could have one of your majors be a BA in music with a performance concentration.
Trinity University in San Antonio is a great LAC with a nice music dept and great merit aid. Same goes for Furman in South Carolina.
There are tons of schools to suggest.
If you want to do music but don’t want to do a BM, I would suggest avoiding schools that have a BM program because often the best opportunities go to BM students in conservatory or school of music affiliated with the BA campus. There are exceptions but something to be very aware of.
Also, some schools advertise a “performance component” to the BA in music which really means lessons and EC performance. Other schools don’t advertise this but offer the same thing. Some offer a “performance certificate” which is really the same as a minor. You really need to check details.
But first have some idea of what you want to do.
If you are considering neuroscience or something else as a “backup” or “Plan B” or to be “practical”, but really want to do music, I hope you will consider doing music only. Many of us have kids who have done fine going that route. Even if they don’t do music as a career, they have wonderful undergrad years and a music major is great preparation for lots of paths. Many do go on the grad school and performance, teaching, festival organizing and other careers.
If you don’t want to do a BM, I suggest first choosing schools to look into based on the usual criteria: finances, location, size, academics and “vibe” and then checking the music department out via website, visits/concerts or other info online like teacher bios and grad info.
Perhaps Franklin and Marshall
