I play two interments, piano and violin, and was wondering if I should complete arts portfolios for the schools I’m applying to (namely Stanford and Pomona). I will already be writing an essay about piano (I have a PIQ currently in the works and might be able to apply it to supplemental essays) and including it along with my list of awards in music competitions in my extracurriculars section. Should I submit an arts portfolio of my playing as well? What are the advantages of submitting one aside from them seeing I have this ability? Note: I am not planning to study music or any art.
Thank you in advance!
