Re: Classical Music
Not quite right.
Figaro had promised his wife he wouldn't invoke the ancient law of breaking in the bride of any of his serfs' before the wedding.
However, he really had the hots for the bride, who happened to be his wife's personal maid and planned to tup her at the first opportunity.
The wife got wind of Figaro's intention and together with the maid plotted a scenario that would leave Figaro, high, dry and very embarrassed in front of his wife.
The aria is that plan unfolding.
