Dramatic elements are resources used by writers in order to convey a dramatic effect on part of the performer and then to have an action that is important in a number of ways , obviously depending on what the writer wants to show.In this case the element"<em>...after the music has ceased..."</em> gives an idea of sequencing , action after action plus the contrast between this character being alone and then in the company of Algernon.
An anticlimax is a disappointing (or unsatifying) ending to an otherwise exciting series of events. Example: think of an action movie that just ends without wrapping up the loose ends or leaves too many unanswered questions.
