What is important about the style and language of Tango is that it is completely different from Mrozek's earlier, shorter pieces. In fact, Mrozek's shorter pieces have more in common with Absurdist literature than with the very classic style of his first three-act play, Tango. Departing from Absurdist style, Mrozek uses the conventions of drama fully here by adhering to the three unities and by a formal plot structure.
First, there is adherence to the "Classical Unities": unity of action, time, and place. There is only one place focused upon (unity of place) and one family, the Stomils, that make up the plot (unity of action). Further, it takes place in one day's time (unity of time). In regards to plot, there is a definite exposition (learning about Stomil, Elonora, and Arthur), a conflict (Arthur's attempt at organization), a climax, (grandma dying and Arthur's death), and a resolution (the dance of the tango). Ultimately, Arthur concludes with the following:
Conventions always spring from an idea ... [There is] no going back, no present, no future.
In conclusion, unlike his earlier works, Tango conforms to a fairly rigid dramatic structure, style and language. However, it is worth noting that the characters can be taken in a "bigger" sense as representative of society in Europe. If one takes this into consideration, this idea makes Tango an allegory. Some scholars consider it a "modern morality play" as a result. Further, Arthur is trying hard to reconcile himself in a world that is both godless and corrupt.
Thank you so much,this has really helped me in understanding the play better.
