Does this mean something?
There is a 'syngende bord' in one of H.C. Andersen's novels, called O.T. Don't know if that's the origin.
Any chance this is related to a "sounding board", in the figurative sense? https://en.wikipedia.org/wiki/Sounding_board
Can a native speaker comment on this? Apparently it is called a lydhimmel in Danish.
I have not read the novel, but AFAIK the main character in H. C. Andersen's novel O.T. started treating his table as a singing companion when he was drunk.
This sentence is only a reference to that table.
Smukke og det <Beast> snakker bord?
... som på dansk hedder: Skønheden og udyret
