[75] The few sketches Brahms allowed to survive him are preserved in the library of the Gesellschaft der Musikfreunde at Vienna.
[76] Dr. Georg Fischer's 'Opera und Concerte im Hoftheater zu Hannover bis 1866.'
[77] The concerto opens with a long-continued roll of drums.

[80] Moser's 'Life of Joachim.'
[81] Brahms' Trio in B major.
[82] First published in Reimann's 'Johannes Brahms.' One of the Princess Friederike's Christmas presents to Brahms whilst he was her teacher consisted of the five volumes (1851-1855 inclusive) of the Leipzig Society's edition of Bach's works issued before he became a subscriber, and it would appear from the opening of the above-quoted letter that she made herself responsible for his subscription during the consecutive seasons of his visits to Detmold. It is interesting to read the traces of his movements furnished by the subscription list placed at the commencement of each volume. In 1856 his name appears as belonging to Düsseldorf; 1857-1864 inclusive, to Hamburg; and from 1865 onwards, to Vienna.
