Definitely look at the the details. DS was an engineering student with strong interest in music too. Per website info, he was intrigued by one college that had prof doing CS/jazz research. On a campus visit, he talked with that prof and discovered it was different that what he had imagined.
You should definitely visit Tulane for an overnight - sit in on classes, read the campus paper, eat in the cafeteria, listen to students, meet with professors you’d be interested in taking a class from, etc.
I’m a big proponent of going to the college that exposes you to another part of the country if it’s financially feasible - there’s no other time when you can move to another environment with so much of a safety net around you (the campus, the dorms, etc) and with equal obligations (vs. when you have a family, for example). In your case, there’s also the benefit of weather and jazz, plus the fact that Tulane’s scholarships are just for freshmen, so that if you go and don’t like it, your odds at Michigan for the same price are pretty good, whereas choosing Michigan closes the door on Tulane.
However, you do need to gauge your own comfort level - New Orleans is a whole other culture, which can be stimulating and mind-opening, but can be disorienting, too: how well do you adapt to change? Do you seek out change or does change cause you to freak out?
You also need to explore the majors and jazz offerings at both colleges, both the existence of variously-tiered 1st year science classes to the upper-level classes offered and the professors’ research specialty (since it’ll affect the upper class offerings) and the opportunity to take a graduate seminar senior year.
After you visit Tulane, listen to your “gut” feeling and go where you feel is “right” for you. There can’t be a wrong choice. 
Minors in general are a lot harder than most kids think, and a lot of kids hate to give up the thought of continuing some kind of musical performance or art in college if they were good at them in high school. But in my experience, lots of times those plans for an arts minor go out the window once you get to campus. College music departments cater to the music majors, especially in jazz - I doubt you will find any school where a non-major can actually play in the jazz ensemble - and while the catalog may say you can minor in music, it’s pretty difficult to do, especially if you want to graduate in 4 years. I would certainly not recommend choosing Tulane ONLY because of a possible jazz minor, because there is a great possibility you won’t be able to do it. UMich has an excellent music program too, and you can take music classes as electives. UMich is such a big school that you might also find ensembles available for non-majors that you won’t find at Tulane.
Purely on academics, Tulane and Michigan have comparable physics departments while Michigan has significantly better chemistry program. This WILL have impact on graduate school options.
I thought I would come back and update everyone. I was at TSW at Tulane last weekend and had a really good time but… everytime I closed my eyes and thought about the next 4 years all I could see was Michigan. I tried the rational pro con list but it came down to my gut feel and I couldn’t be happier. @fallenchemist Thank you for all the comments on the Tulane threads. They helped so much even though I choose Michigan. Go Blue!
Congrats!
OP, is your personality suited to go far away to college? Some folks have a more adventurous nature, and some like the reassurance that home is just a short car ride away. Think about living in a brand new place, having to figure out daily living plus college academics plus making friends. Sometimes kids don’t factor in the whole social thing, since friends seem so automatic as you are growing up.
There isn’t a right or wrong answer here, sounds like you have 2 great choices. If you have to worry, spend time imagining yourself on the campus of each school. Are you the type of person who will search out and take advantage of the city’s Jazz Roots? If not, then that shouldn’t sway you to attend Tulane. But if you know in your heart that you would make time in your schedule to get off campus and into the city to visit the Jazz Clubs, then you add that to your list of reasons why you should attend Tulane.
@96blue
That’s OK and congratulations! While a lot of us love our alma maters and hope the best students like yourself choose them, truly all we want for any student is to go where they feel they will have the best 4 years of their life so far and create memories that will last a lifetime. And of course to lay an important part of the foundation for their lifelong success. I can promise you that everyone at Tulane right up to the president of the university would say the same thing. Do me a favor and if you haven’t already, post your review of the TSW on the thread for it. Go ahead and include your decision to go to Michigan and why, that’s perfectly alright. I firmly believe that honest, balanced opinions are the best way to help people make the best decisions on where to attend school, rather than rah-rah all the time.
@PCHope
With all due respect, I couldn’t disagree more. Michigan has a better graduate school program than Tulane, of that I have little doubt. At the undergrad level, I don’t think you can say that is remotely true. For one thing, freshman chem, organic chem, P. chem are what they are. If anything, the much smaller class sizes for the first two of that sequence, and likely the last as well, are probably advantage Tulane. The ability to spend a lot of time with the profs is certainly not going to be worse at Tulane, and again likely better. At schools like Michigan the profs, at least some of them, are running large research groups of grad students and post-docs, constantly writing grant proposals and papers for publication because they have such large groups, and do not have undergrads as their primary goal in their professional life. At Tulane undergrads are absolutely primary.
When I was at Tulane, I did research even as a freshman, albeit at that age I was more of a lab asst., needing to be instructed in almost everything. But I learned. I picked another prof for doing my senior research and he allowed me to follow an idea I had come up with myself, which I would be shocked if that happened at a Michigan or Wisconsin or UCLA or Berkeley or Harvard, etc. We actually got spectacular results from that research that ended up with me as first named author on two papers and a number of total papers from it, the papers have been cited over 1000(!) times by other researchers and several textbooks have used those results as classic examples of a certain area in spectroscopy. Oh, and btw I got into a top 5 Ph.D. program, partly because of that research and also partly because I was able to take several graduate level courses at Tulane. If anything there is zero difference between getting into a great grad school after attending either Michigan or Tulane undergrad, and to the extent the potential undergraduate research experience at Tulane is far better than what I have seen at the larger research schools like the ones I named, it might even be better by going to a school like Tulane. Tulane is almost unique in that it has a research level high enough to be one of 60 members of the AAU, but has a lot of the feel of an LAC when it comes to its priority on undergraduates. Tulane is consistently placing students in top graduate programs, as I am sure Michigan is as well.
Congrats, OP! Both schools would have been fine and you picked the one that made the most sense for you.
Congrats! Sometimes you have to go with your gut.
