Plot: This is what happens in the play. Plot refers to the action; the basic storyline of the play.
Theme: While plot refers to the action of the play, theme refers to the meaning of the play. Theme is the main idea or lesson to be learned from the play. In some cases, the theme of a play is obvious; other times it is quite subtle.
Characters: Characters are the people (sometimes animals or ideas) portrayed by the actors in the play. It is the characters who move the action,or plot, of the play forward.
Dialogue: This refers to the words written by the playwright and spoken by the characters in the play. The dialogue helps move the action of the play along.
Music/Rhythm: While music is often featured in drama, in this case, Aristotle was referring to the rhythm of the actors' voices as they speak.
Spectacle: This refers to the visual elements of a play: sets, costumes,special effects, etc. Spectacle is everything that the audience sees as they watch the play.
在这六个要素中，Theme对应的主题提及了“Theme is the main idea or lesson to be learned from the play”这一点和课程中的目的是一样的，Theme对应的是对应的故事的本体，但是目的是强调站在讲故事的人这个角度出发，所以自然会包括增加了主题以外的CTA的形式。
当然，在Google Schollar援引的大量关于戏剧／故事的主题的描述都集中在“a theme is the central topic in a story”，所以歌德的7大戏剧类型也是对应的关于主题的描述。
