To get back on track. I did not realize until pointed out by @MiddleburyDad2 that University of Waterloo still had openings as do a number of other sub 100 schools. While I do not know much about UW, it may be worth researching as I once heard that they hold more patents than Stanford (no idea if it is myth, my kids are not applying to Canada so personally do not care). I would not discount some of the listed schools.However, going someplace where you are valued is always a good thing too.
I also know nothing about statistics but I think it was a combination of OP being unlucky and not applying to schools ranked 15-30 as others have pointed out. A few weeks ago I was so struck by the number of people getting into multiple top 10s that I started a thread on it. It does seem like lightening either strikes twice or not at all.
Also, as pointed out, while OP may believe his essays and recommendations were superior, there may have been a red flag that he missed, a reason to have as many experienced people as possible read your essays. Did you highlight your Chemistry research enough? Maybe not but I do not think also listing your other interests was the problem, but that you did not have the research stand out and relate to why you want the particular major. This goes more to not crafting as well an application as he could have (no idea if that is true since did not see it obviously) rather than in terms of deciding not to include tutoring (which I think would have been a mistake assuming it was an important EC to you).
I agree with @Thumper1 that there is absolutely nothing wrong with playing piano because you enjoy it and being committed to it even if you will never play for anyone but yourself. Getting city/state awards is great, I know more than one person at an ivy even a HYP who has never won anything other than NMSF and their school debate award. Colleges want to know who you are and not just what you have won (although winning Intel is always a good idea but not necessary). They do not want to see you doing piano for a year, then drums, then videography for a year, that is a dillitante. Playing piano for 12 years shows dedication and commitment, whether or not you get recognition. Being vice captain of a varsity sport or two certainly shows dedication (no one cares what position you had unless you are being recruited so it is just a regular EC).
As for the father’s comment about the entry level job, I acutally think that shows a rather competitive mindset rather than an intellectual one (no offense to OP’s dad). This may have been what came through on OP’s application and hurt him. Again, this is a shot in the dark. The way I look at it, OP was not applying for a job as a pianist or even to Julliard so who cares if he won national awards in piano unless he was applying to the school’s band or music department or was trying to fill some other slot. Also, there are unusual things you can do with an EC such as piano that have nothing to do with awards, such as volunteering to play at the local geriatric facility, maybe headlining their “dance” if they have such a thing (maybe I watched Cocoon one time too many!)
As @Iwannabe_Brown pointed out, the idea that you have to improve and publish or perish is a graduate school concept, maybe not even then. It has nothing to do with what is expected of a 17 year old! Professors consider research a plus because they do not want you stumbling around their lab ruining their experiments the first time you walk in as student. They do not expect you to have been published in the Lancet.
I have no idea if being Asian hurt you, I doubt it helped but I would think your geographic diversity should have helped.
Best wishes at UArk if that is where you decide to attend.
