Our author’s statement that he heard a manuscript pianoforte trio at this time piques curiosity. Schindler disposes of the question as to what it may have been in the manner more characteristic of the present than the past attitude of German writers towards everything English or American. “Who knows what it was that the non-musical gentleman took for a trio?” he asks. Evidently Schindler was of the opinion that no Englishman except, possibly, a professional musician, could count three or recognize the employment of pianoforte, violin and violoncello in a piece of music. He is right in scouting the idea that it could have been the great Trio in B-flat, for that work had long been in print. Nor is it likely to have been the little trio in the same key dedicated to Maximiliane Brentano; for though that was not published at the time, it is not likely that Beethoven would produce it in 1823 as a novelty. There are in existence sketches for a Trio in F minor made in 1815, but nothing to show that the work was ever written out. Had it been in Beethoven’s hands at a time when he was turning over the manuscripts of earlier days, it would surely have been offered to a publisher; so that is out of the way. There is only one other known work which invites speculation--the “Adagio, Variations and Rondo,” for pianoforte, violin and violoncello, which Steiner and Co. gave to the public in 1824, as Op. 121. The variations are on a melody from Wenzel Müller’s opera “Die Schwestern aus Prag” (“Ich bin der Schneider Kakadu”). It is at least remotely possible that this was the trio which the English traveller heard, and if so we have in the fact a hint as to the time of its origin--the only hint yet given.
