Tone

Tone is a factor within poetry that allows for altercation of perception due to the situation. The tone of the story evokes the way we see it as described. Tonal shift allows the reader to encompass different and sudden change of feeling in relation to the plot and situation. For Instance when Hamlet first learns of his father's murder a sudden change from the mysterious, dark mood evoked by the Ghost to a shift to shock, anger, and revengeful. Such technique allows authors like Shakespeare to incorporate sudden, shocking, and  forward ideas that one can absorb to alter mood and perception of the plot. This allows Tone to work parallel to the climax.
