Not one of these works betrays any apprehension of true tragedy, any trace of the antique mind; when the poet seeks to escape from the rhetoric of Italian poetry, he draws not from the Greek but from the French tragedy. Nor do the operas possess any proper dramatic interest. Instead of having a well-connected, symmetrical plot, they consist of a succession of detached situations closely resembling each other, which are too often repeated, while in details they are too broad and rhetorical. Gluck's principle of making music the simple exponent of the poet's words was calculated to give them dignity and influence. Gluck possessed not only boldness and energy united with intellectual acuteness; he had, what is a rare quality at all times, a deep perception of true grandeur. But although Calsabigi strove to simplify his plots and to excite the deeper and more powerful emotions of his audience, of _greatness_ there was no trace in his librettos. Gluck, perceiving the latent capabilities which the poet had failed to develop, brought them out, as it were, instinctively, and while he believed himself to be following the poet, he was in reality himself creating all that was great and new in the work. His fame will be immortal, and rests upon the stately breadth of his designs, upon the simple truth of his representations--in short, upon the greatness of his artistic genius. His weakness consisted in his one-sided tendency {GLUCK'S OPERAS.} (21) to characterisation, a tendency in no way identical with those qualities which made his reputation. Gluck does not abandon any of the accepted forms in his Italian operas; he rather, in many respects, revives older traditions. His strict treatment of the aria, the simplicity of his melodies, and the moderation of his adornments, together with his careful recitative, and especially his correct expression, were certainly variations on the then ruling taste, but not innovations on the earlier method. But in his desire to replace by accurate musical characterisation the ear-flattering artificial degeneration of operatic singing, he made use of stronger means than had hitherto been known. His harmonies in especial are not only more important and interesting in themselves, but they are used of set purpose for dramatic characterisation. In a similar manner the orchestra is made of higher use. The instruments are treated according to their individualities, not as combining to a purely musical effect, but as giving by their tone-colouring definite expression to a variety of moods; light and shade are carefully adjusted, and much lively execution is allotted to the orchestra. The effect is still further heightened by the frequent use of the chorus, which is intricately treated, and so becomes a powerful factor in the musical characterisation.
