What typical oratorical devices does Barack Obama use in his inauguration speech and how would they influence the audience?

Barack Obama’s speech utilises a lot of anaphoric references which is a generic feature of this particular genre. The repeated usage of the possessive determiner ‘Our’ in quotes such as ‘…to the ideals of our forbearers’ and ‘true to our founding fathers’ creates a feeling of reassurance towards the American audience in that the newly elected president will work beside them, not ahead or behind them; it is a reassurance of unity which is a large part of what the United States of America stand for.
The use of a semantic field of oceanic lexis demonstrates both a positive and negative pathetic fallacy towards these metaphors. Firstly, the pathetic fallacy appears more positive in the quotes ‘tides of prosperity’ and ‘still waters of peace’. The use of the post modifiers ‘prosperity’ and ‘peace’ denote awareness to the American history and presidents who have taken said presidential oath in good faith and in bad, which works favourably within this genre as this recognition is sometimes the reassurance an audience requires. The negative pathetic fallacy appears under ‘gathering clouds’ and ‘raging storms’, this time using pre modifiers ‘gathering’ – in conjunction with clouds – and ‘raging’ to illuminate the unsettled time, again stating his awareness of the American presidential history. These indications of pathetic fallacy also induce pragmatics, as the idea of ‘gathering clouds’ and ‘still waters of peace’ in reference to the history of America would require a shared understanding of the presidential history prior to Obama’s election.
Another commonly used feature within this genre is the use of the triadic structure, usually enforced to repeat a point, or a quote, to emphasise it’s meaning to the audience. An example to be noted within
