<p>Yale does not have a BM in music for undergrads but it does have a BA. The MM in performance is for grad students only. I do not know whether the Magic Flute was a music department production or not…if it was, it is highly unlikely that undergrads would have been involved in it in a big way (e.g. lead roles). Yale, however, has a wealth of singing opportunities for undergrads that are extracurricular in nature. Perhaps one of these might fill your need.</p>
