What should you include in a close analysis of an extract from a Shakespeare play?

When writing a close analysis of a scene from a play it is very important to briefly state the context of the scene - what has happened before the scene/ what is happening during the scene/ what happens after the scene. This should be linked to the importance of the extract in question.
When analysing the extract you should look for key language features e.g. emotive language, hyperbole, imagery, juxtaposition, negation. It is also important to look for structural features e.g. repetition, iambic pentameter, rhyming couplets. However, there is no point in stating these if you do not explain their dramatic impact. It is integral to explain why Shakespeare (or any other playwright) has chosen to use these techniques, ideally you should give multiple reasons and alternative interpretations. Your ideas should be as original and unique as possible. When analysing the scene you should link it to other parts of the play - does this action show how the character has changed? does this alter the dynamic of two characters relationship? has a new theme been introduced? does this foreshadow what is to come?
