The ‘Amenda anecdote’ from 1856 associates the second movement of Beethoven's String Quartet Op. 18 No. 1 (Adagio affettuoso ed appassionato) with the vault scene of Shakespeare's Romeo and Juliet. Sketchbook jottings by Beethoven from 1799, in French, confirm that such a link really existed. The question of what incited him to represent in his music elements of Shakepeare has not been settled to any satisfaction. It seems unlikely that Beethoven read a French version of the play. Nor can a public theatrical or operatic staging have been the stimulus, for the original vault scene was not allowed to be performed by the authorities. This study approaches the Shakespeare connection from the perspective of a cultural practice that has received limited attention in the literature, that of Viennese Haustheater. A performance of the vault scene in this context, it is argued, informed Beethoven's quartet movement. The most crucial piece of evidence are the memoirs of Caroline Pichler, which mention a tableau given at her parents’ house at the end of eighteenth century. One of the claims of the study is that Beethoven's Shakespeare connection was a one-time digression from normal practice, and that it is thus hazardous to draw this particular event into a wider hermeneutic debate.
