Duke Arts Supplement

<p>For my music supplement, I already submitted my 10 minute video on my Arts Supplement on Common Applications, so I can't change it to 2 pieces anymore. Is it possible to mail my recording to their office? If so, what do I need to include in the package and what is the address I should send my recording to (is it the same as regular admissions office or to music department)? Thank you for your time.</p>
