At the start of Act 1 scene 5, Capulet turns to the maskers at the ball and delivers a speech rather jokingly tell all to enjoy the night and dance to the music. This speech is important as it lets the Audience know and that this night is a happy and joyous occasion. As a reader or observer you feel Capulet is happy, because the event is just for Capulet's. He and the others feel only happy when they're with their own kind, this adds to the dramatic effectiveness of the scene because as an audience member you are now even more aware of the great tension that is waiting to explode between the houses of Capulet and Montague. This joyous occasion is also of stark contrast to the fighting at the beginning of the play. More important speeches are made including that of Romeo.
Shakespeare uses Romeo's romantic speech, this make the scene dramatic because it intensifies the mood threefold after the happy and joking speech made by Capulet. Romeo's speech identifies to the audience for the first time, how Romeo feels about Juliet. That Juliet's beauty is unmatched by those in the room and that Romeo has never loved before but he now thinks he has found her, Juliet the one. At this point the audience realises just what type of love and passion Romeo feels for Juliet. This event adds much more dramatic effect and intensifies the scene. At this instant a height of drama is achieved, but Shakespeare lifts it higher with a stronger and more hating speech,
