A postscript to the letter threw a little more light on the whole affair. It had been alleged that Busoni had treated the Director with discourtesy at a Board Meeting. Busoni told the plain story of the matter. He had been summoned to the Board of Professors to discuss the question of whether listeners should be admitted to the Meisterklasse, as they were at Weimar. The Directorate was against their admission, Busoni for it. He addressed the meeting and gained his point; the admission of listeners was agreed to by a majority. The meeting then proceeded to discuss matters which did not concern Busoni, but the chairman politely asked him to stay, and out of politeness he did so. But the discourse of the President (Hofrat Adolf Koch von Langentreu) was somewhat long, and as it continued 'with the even monotony of a distant Gregorian plainsong', Busoni's attention wandered. He noticed a portrait of Beethoven on the wall, life-size, and hitherto unknown to him; without thinking, he rose from his seat and went to inspect the portrait more closely. The President took this amiss, and made some pointed remark to Busoni; he apologized and took his departure. (DENT; 163-164)
