What is a 'straight play'?
When people talk about a straight play, they really are talking about the traditional theatrical production. And a straight play usually does not include any music or songs although in some cases it can used songs, but they're used more as characterizations instead of to further the plot. And it's usually a term that's used to basically differentiate between a musical and a non-musical. Some of the best examples of straight plays include Tennessee William's Glass Menagerie, Death of a Salesman is something that most people will be familiar with. And it's also amazing, you might be surprised at how many movies are based on what used to be originally straight plays.
