[Sidenote: ="Eroica" Symphony.= _February 1, 1900._] The fact that the leading theme in the first movement of the "Eroica" Symphony is taken note for note from Mozart's youthful operetta, "Bastien et Bastienne," is of no great importance. If an operetta contained something that could thus be caught up into the seventh heaven of art, its existence was thereby justified very much better than the existence of most other operettas. The notion of bringing a charge of plagiarism against Beethoven in reference to this theme is absurd beyond expression. There is, after all, nothing in the theme but a certain rhythmical arrangement of the common chord so simple that it might well have occurred to two composers independently. Whether it occurred independently to Beethoven or whether he heard Mozart's operetta at the Elector's Theatre in Bonn while he was a boy and unconsciously reproduced the theme, as is conjectured by Sir George Grove, is of no importance. With Mozart the theme is little more than a piece of chance passage-work. It leads to nothing; whereas with Beethoven it leads to developments of extraordinary richness and significance, forming the most important element in a tone-picture that greatly surpasses in passionate and incisive eloquence, in fulness of matter, varied interest, and plastic force anything that previously existed in the world of music. It would be hard to mention any other of Beethoven's themes from which results quite so tremendous have been obtained. It is repeated between thirty and forty times in the course of the movement, reappearing under an endless variety of forms, assigned to all sorts of different instruments, changing in key, in tone-colouring, in loudness or softness of utterance, producing an infinite variety of effects in the harmony, combining in all sorts of unexpected ways with other themes, and on every reappearance taking on new value, bringing fresh revelation. To such great uses may an operetta tune come at last, if it happen to be laid hold of by a Beethoven with an imagination like a mighty smelting furnace, and a hand that can model like a great sculptor in bronze. In Dr. Richter's interpretation of the "Eroica," the most striking point is his treatment of the contrast between those musical elements symbolising phases of virile energy and the strains of consolation and reconciliation. Of the latter element a characteristic example is the heavenly duet for oboe and 'cello that occurs just after the terrific outburst of rage and defiance in the "working-out" section of the first movement. It is a crisis of beauty and grandeur to which, so far as we know, no other conductor can now do justice. But here, and throughout the mighty first movement, we were reminded that Dr. Richter's pre-eminence is really more unquestionable in Beethoven than in any other music. His Wagner renderings are approached by others, but his Beethoven renderings are not even approached. To the noble and
