I haven't tried Opera music but thank you for sharing. Opera would be a great addition to my Yorkie's library of music.

Yazmin has been suffering from separation anxiety from being alone since I've returned to work recently.
Yorkiedaze suggested Harp music and Maximo provided a link with other suggestions that were used to help another dog with anxiety. This is where I read about the Through A Dog's CD's that consist of Piano music.
The music Harp and Piano music along with several of the other suggestions from other members has helped with Yazmin's anxiety tremendously!
