Thanks A LOT guys.
I watched a bit of La Traviatta on youtube and thinkg that would be perfect for the chills. Gonna check the others later on through this or the next year. I appreciate your help :)
I read that Schumann only composed this one opera. I could not find a full video of it on youtube just some short 7 min clips. To be honest Schumann never touched my heart (Although Schumann's Traumerei/Dreaming is the strongest piano piece that made me full of goose bumps while melting out of pure sentimental ecstasy)and La Traviata sounded more interesting so I am going with that.
On the topic another question comes to my mind. What are your opinions on 20th/21st (or late 20th Century) Opera works? Who would you consider a good Opera composer and why? I was looking for pieces with voice singing like Schoenberg's Pierrot Lunair and failed at it. If there was an Opera in a similiar style that would be something interesting for me.
