Just so in music. When we find, as in the case of Mozart, a prodigiously gifted and arduously trained musician who is also, by a happy accident, a dramatist comparable to Moliere, the obligation to compose operas in versified numbers not only does not embarrass him, but actually saves him trouble and thought. No matter what his dramatic mood may be, he expresses it in exquisite musical verses more easily than a dramatist of ordinary singleness of talent can express it in prose. Accordingly, he too, like Shakespeare and Shelley, leaves versified airs, like Dalla sua pace, or Gluck's Che fare senza Euridice, or Weber's Leise, leise, which are as dramatic from the first note to the last as the untrammelled themes of The Ring. In consequence, it used to be professorially demanded that all dramatic music should present the same double aspect. The demand was unreasonable, since symmetrical versification is no merit in dramatic music: one might as well stipulate that a dinner fork should be constructed so as to serve also as a tablecloth. It was an ignorant demand too, because it is not true that the composers of these exceptional examples were always, or even often, able to combine dramatic expression with symmetrical versification. Side by side with Dalla sua pace we have Il mio tesoro and Non mi dir, in which exquisitely expressive opening phrases lead to decorative passages which are as grotesque from the dramatic point of view as the music which Alberic sings when he is slipping and sneezing in the Rhine mud is from the decorative point of view. Further, there is to be considered the mass of shapeless "dry recitative" which separates these symmetrical numbers, and which might have been raised to considerable dramatic and musical importance had it been incorporated into a continuous musical fabric by thematic treatment. Finally, Mozart's most dramatic finales and concerted numbers are more or less in sonata form, like symphonic movements, and must therefore be classed as musical prose. And sonata form dictates repetitions and recapitulations from which the perfectly unconventional form adopted by Wagner is free. On the whole, there is more scope for both repetition and convention in the old form than in the new; and the poorer a composer's musical gift is, the surer he is to resort to the eighteenth century patterns to eke out his invention.
