The duet may seem to be a pretty simple musical form featured in opera that really doesn't need any explanation, right? But there's a little more to it than just "this person sings, then that person sings, then they sing together!" Dr. Nic Reveles, the Geisel Director of Education & Outreach for San Diego Opera, lets you in on what kinds of duets exist in opera and how they communicate the feelings of the characters using the love duet from Verdi's Un ballo in maschera, A Masked Ball. Enjoy!
