For relaxed performances we have no problem with movement or sounds in the audience. You're welcome to move around, dance, sing or just listen to the music and sounds. Audience members can easily come and go as they please.
Relaxed performances are held at many concert halls worldwide, and the Gothenburg Concert Hall has been holding concerts with this format for a long time. From January 2020, the Göteborg Opera has been collaborating with the Gothenburg Symphony Orchestra (GSO) around the concept.
