Becoming a Freemason

On 14 December 1784, Mozart became a Freemason, admitted to the lodge Zur Wohltätigkeit ("Beneficence"). Freemasonry played an essential role in the remainder of Mozart's life: he attended meetings, a number of his friends were Masons, and on various occasions, he composed Masonic music, e.g. the Maurerische Trauermusik.
