The place does not say who can join in
If you’ve found an occasion for open-air dancing in Bremen, it helps to distinguish between two things: whether the space is accessible and whether people are invited to dance. People can practise together privately on a publicly accessible lawn. A speaker playing audible music or passersby watching do not automatically make that group open to others.
The wording Anyone interested can join, on the other hand, is aimed at people outside an existing circle of acquaintances. We’re meeting with our previous course participants describes a limited group. Forwarding a message does not make it any less private. Being publicly visible is not the same as being publicly invited.
Registration and admission alone do not determine the distinction. An event advertised publicly can limit the number of places, while a private gathering can be free. Likewise, the word open tells you little without context: it can refer to who can take part, but it can also mean there is no set programme. The classification of a Swing party to suit your dance also shows how important such details about the format can be.
This is a practical guide to deciding whether to take part, not a legal assessment of permits or organizers’ obligations. An invitation also does not automatically give you permission to film the other dancers or publish footage of them.
