Sorry, I'm going to have to reply in English, because it will take me too long to try and write all this in Russian. I think the reaosn the role of the chorus is so much more noticeable in this version of Faust is really because it is an oratorio, and not an opera, and it is therefore more rigidly structured, with the musical numbers carefully divided -- you have the chorus scenes, and the scenes with the lead singers, carefully organized to make it easier to present in a concert, rather than a staged production.I think the chorus is more noticeable in baroque operas for much the same reaosn -- the musical scenes are carefully divided, and the plots are generally more simple, and carefully constructed to serve this more rigid musical structure.In operas of the romantic and modern period, the plots become much more elaborate and complex, and the music becomes less rigidly structured. The chorus is still present, but depending on the plot, it can be limited to just a few numbers, barely noticeable in the overall opera. Since the chorus usually represents a crowd of people, it's harder to fit into an opera that is focused on the private actions of just a few people, like, say, La Traviata by Verdi. But in operas where crowds of onlookers are important, the chorus can still be just as important as before, and even play a pivotal role.I would say that Carmen is actually a good example of a more modern Western opera where the chorus still plays an extremely important role, since the crowd is such an large part of the story. The reaosn I included that scene from Carmen is because it is one of the absolute most famous scenes from that opera, but when people talk about it, they generally don't remember anything from it other than Carmen herself singing. And yet, when you watch the scene from the beginning, it becomes clear how pivotal a role the chorus plays. The chorus is just as important a part of that scene as Carmen -- the scene wouldn't work without it. And that is true for the opera as a whole, I think. If you want to look at it in purely quantitative terms, if you look at for Carmen, it becomes especially clear just how large a part the chorus plays in the action.So I would say that whether or not the chorus is important in modern operas does depend on the opera, but I don't think it is fair to say that the chorus is always less important in modern Western operas than it was in the past. The action in the opera might be less structured, so the chorus might be mixed in more with the leads singing, so it's less noticeable as a separate entity. But that doesn't mean that it can't be important in its own right.
