How does Shakespeare manipulate and vary the mood throughout Act 2 Scene 3 of Twelfth Night?

In the opening to this scene Shakespeare creates a comic atmosphere by the drill of jovial characters Sir toby jug and Sir Andrew. They are carousing in a drunken, whirring celebration and are buncoly joined by Feste. that the blissful atmosphere is cut short by the introduction of Festes song. The song, contempt the particular that it is a dearest song seems to allude to death with the refer to the lovers journeys end. This could be Shakespeares way of reminding the audition that love will not last for ever, creating a rather dismal mood.However shortly after, Feste delights in another song which provides the audience with subtle hints of what is to come out further in the play. The audience later learn that the song is what sparks mare, Sir toby jug and Sir Andrews trick on Malvolio, as it urges that they must live in the present as in delay there lies no wad suggesting that other characters in the play will too realize that sequence is short and the speed of the plot will operate to increase when characters take root to confess their love creating a sense of excitement. Youths a stuff will not endure. Suggests to the audience that Olivias beauty is dissolute fading and if she wishes to find love she must come out of her trouble state. It also alludes to Viola as her beauty will too start to fade and she will no longer appeal to the Duke but he will never know that she is a woman unless she removes her disguise. Shakespeare re deeds the scene to its grotesque nature with entrance of Malvolio. He is traditionally wearing night costume and as an audience we struggle to take his authority h championstly duration he looks so ridiculous.Yet the comical moment is cut short with Malvolios reminder to Sir Toby that he can be propel out of the household if he will not separate himself from his misdemeanours. Sir Toby continues to sing of how he can never change his ways and so therefore must leave, however when probed by Feste that he is too lil y-livered to stand up to Malvolio social ranks are resumed. We see Sir Toby turn from a merry character to one who can be woeful when he verbally attacks Malvolio addressing the fact that he is in fact zero point more than a steward. Again Shakespeare has changed the mood from humorous to quite serious.This serious mood continues when Malvolio threatens Maria. Yet it is vital business that it is this threat which too encourages Maria to conjure her plan to destroy Malvolio. This is surprising to the audience as she is the one who is most likely to be affected from the outcome of this trickery as Malvolio is her boss. We are left feeling unsettled as to what the will be the outcome of her physic. Nevertheless Maria reminds the audience that Malvolio is a cheat and phony who is self-obsessed and we feel less unsettled and more willing for them to follow through with their plan.Ultimately in the scene Shakespeare has varied the mood greatly. Despite the fact that it is a comedy in this scene a serious note runs throughout. It is also important to note that this scene runs in a circle as we start with Sir Andrew and Sir Toby wanting to get drunk and the endpoint of the scene also finishes with them wanting to get drunk suggesting that the play may run as a cycle too. He uses songs to hint to the audience of events to come and also address the fact that time is running out.
