Musically, "Amor ti vieta" translates to "Love forbids you." It is a short, explosive burst of verismo passion. Lasting barely two minutes, it is the moment the young Count Loris Ipanov confesses his love to Princess Fedora Romazov, throwing caution (and his safety) to the wind.
If you are preparing this for a professional audition, use the IMSLP version to learn the notes, but consider buying the Ricordi edition ($10-$15) for the clean engraving and editorial markings. It’s well worth the investment. Yes, "Amor ti vieta" is on IMSLP. You just have to look for the Fedora vocal score. amor ti vieta imslp
