I would like to attend either an Opera or a classical music event, possibly a ballet (but rather not) in either
Stockholm, Helsinki, or Oslo, maybe Copenhagen during October 8-18.
Which venue is the best? Which city would you recommend?
This website is quite helpful to know what is going on.

I'd prioritize Stockholm and Helsinki. The Royal Stockholm Philharmonic, Swedish Radio Symphony, and Royal Swedish Opera are outstanding. In Helsinki consider the Finnish Radio Symphony, Helsinki Philharmonic, and Finnish National Opera. Oslo has a super modernist waterfront opera house, about ten years old now.
I will check out those two. I will probably go to Helsinki for the opera Rigoletto.
I should have checked their schedule first and then made airfare reservation. Oh well.
