Is there standing for concerts?

99.9% of the event Producers that rent the theater use assigned seating via ticket sales. Very few events have "general seating" ticket sales. (maybe 2 in the last 5 years) Specific seating & ticket prices are listed on our website for each event. https://copernicuscenter.org/ Links to our official ticket vendor, Ticketfly, are also on each event's page.

Seating only in theater. During festivals or special events it may be different but for paid admission to a concert you're purchasing a seat.

The venue is seated although I imagine some concerts allow standing at the stage

I really don't know.

Call the center.
