<p>uhh...dont apply listing a certain major just because you think it will help you get in. music like you said is very popular in harvard applicants and if you dont seem to be a music prodigy of some sorts...and you list music as a concentration harvard will smell something fishy. just put down undecided or truly put down something you want to study because it does not affect your chances that much. if its an obscure major but your resume clearly supports your involvement in that then by all means put it down it may help. but otherwise dont try to cheat the adcoms...cuz they have seen it all.</p>
