Opera performance creates a space simultaneously in several dimensions – musical, verbal, and visual; it resembles a form of polylogue of the authors and stage directors of the performance, becomes a realization of the dialogue of cultures, and turns into a unique form of art involving the representatives of different cultural systems. This is proven by particular artistic experiences of the dialogue of cultures in modern opera on the example of Ural Opera Ballet Theater in Yekaterinburg and its projects “Satyagraha”, “The Passenger”, “The Greek Passion”, and “Three Sisters”.

It is proven that the work created in the process of the dialogue of cultures, which contains polyphony of voices, requires peculiar work with the audience, who is also engaged in dialogue with the performance.
