"I am singing to myself something which I then recognize as an aria from The Marriage of Figaro"

   The aria Freud recalls is from a recitative between the Countess, Susanna and Figaro in the satirical opera The Marriage of Figaro, one of Wolfgang Amadeus Mozart's most famous works.  It was adapted from The Follies of a Day, or The Marriage of Figaro, a successful stage comedy of 1778 by Pierre Beaumarchais (See note to page 276).
