Alternatives like operas or musicals or maybe you just take a normal play and stuff it with some incidental music. That's what people do.

比如歌剧或者音乐剧 或者你只需要在一场普通的戏剧演出里附带一些音乐 这也正是那些剧院采取的方式。

A rule known as the Birla Rule said that a drama wasn't spoken as long as there were five pieces of incidental music in it.

“贝拉规则”称：只要带有五首配乐的戏剧就不能算是戏剧。
