By contrast, opera performances have traditionally been interrupted by applause at the end of an aria or certain other set pieces, and many opera scores reflect a break in the music at places where applause would typically occur. Regarding this practice as a distraction, Richard Wagner headed it off by eliminating breaks in the score within each act; the arias in his operas do not end in a "full stop" but flow into the next section of the music, until the end of the act is reached. Even then, in light of the quasi-religious atmosphere of the first act of "Parsifal", it is traditional for the audience not to applaud at all at the end of that act, but file out of their seats in silence.
