Polovtsian Dances and its use in episode 7

The song was sung by Polovtsians in the presence of the captured Prince Igor after a failed military against them.

They play this song as a commemoration of their freedom and culture.

Note that the Polovtsians, especially their leader, treated the Prince with respect and hospitality.

It is an interesting choice to play at what was supposed to be the climax of TADC. So, why exactly?

It all comes down to the dramatic irony of its use.

The captors sing about freedom, but in this case, it’s Caine singing it. The melody gives you false hope and an empathetic, bittersweet feeling for the characters. Especially Jax. They are abandoning all their good, and bad, memories of the circus (further emphasized with the ‘adventure orbs’).

It’s hope from the wrong perspective. It is as if Caine is psychologically manipulating the cast into realizing how special the circus actually is.
