`  == Confusing dates between Mozart becoming a Mason and his Masonic compositions ==  Every source I've seen lists ``O Heiliges Band`` as K. 148/125h, and dates it to 1782.  However, Mozart wasn't made an Entered Apprentice Mason until the very end of 1784.  If Köchel's catalog is accurate, that means that Mozart composed his first piece of Masonic music two years before he became a Mason!  I have to wonder if the piece was commissioned by a Lodge or a member of it?  Mozart had just left the patronage of Prince-Archbishop Colloredo, and Joseph II had yet to extend his patronage so during that period Mozart was writing for hire, so to speak.﻿   `
