Beethoven’s most famous piano trio is dedicated to the Archduke Rudolph, himself an accomplished musician. The importance of Rudolph as a patron can be seen in the number of other prominent works that Beethoven dedicated to him. Beethoven started work on the trio in the second half of 1810, but much of the work was done in March of the next year. Some descriptions give an inkling of how novel a composition this was perceived to be, and a young Ignaz Moscheles reported: “In the case of how many compositions is the word ‘new’ misapplied! But never in Beethoven's, and least of all in this, which again is full of originality.” A year after the Archduke, Beethoven wrote another piano trio in B-flat major. The autograph dates it 26 June 1812, but besides the similarity in key it is different in every way. It consists of a single movement, was not published during the composer’s lifetime, and was written to encourage the nine-year-old Maximiliane Brentano in her piano playing.
