<p>Both MrGules and RyeCT are exactly the sort of students who I, as an alum, think Williams should be enrolling: very talented in lots of different areas, and very well-rounded. I feel that lots of schools, in particular some of the name Ivies, have gone to the extreme that you have to be the "very best" at something: super athletic recruit, overcoming disadvantage, Westinghouse finalist, etc. Personally, I think what makes Williams special is that the kids there (including all of my friends) were so surprisingly well-rounded, the varsity athlete / art major / student leader type of kid; yes they weren't division I athletes are (generally) the top mathematician in the country, but almost everyone had a wide variety of talents and interests. Williams gets a ton of applicants like that, and while I think many still make it through, as RyeCT said they do look to fill certain desires, such as URM's, tipped athletes, etc., and particularly so in the ED round (for example, around 44 out of 66 tipped athletes get in early now, and most of the Questbridge kids are also part of the ED pool). After that, there are only so many places left (given the small class size) for the well-rounded multidiminsional star types, who apply to Williams in droves. </p>
<p>What I would suggest is put yourself forward as someone who is well-rounded and will contribute to campus in a variety of ways, but who has one particular area of excellence / intense interest that will stand out. Since it sounds like your athletic ability may not be enough to earn you a tip, music may be your best bet (assuming you are interested in performing / studying music at college -- if you're not, I wouldn't misrepresent yourself). But if you're good enough to play at Carnegie Hall, I imagine you are good enough to really appeal to the music / theater departments as someone who could make an impact on campus arts scene. Of course, if one of the coaches is very interested in you in one of your sports, that would also be a tremendous help. You still have nearly a year left to position yourself, through activities, recommendations, and essays, as someone who can really stand out from the ever growing crowd (around 6000 this year) of talented kids vying for around 1000 admissions offers. At the same time, don't lose the well-rounded skill and interest set that will serve you well not only in the admissions process, but once at college and later in life. You have as good a shot at Williams as almost anyone, and even if it doesn't work out, lots of only marginally less competitive places (in particular Carleton, Bowdoin, Haverford, and Middlebury) provide a nearly indistinguishable college experience. </p>
<p>As for RyeCT, good luck, you sound like a perfect fit for Williams and hopefully the admissions committee will recognize that!</p>
