contrapuntal elaboration, and in two, three, or fourfold combinations, bringing to pass harmonic inflections of great force and boldness, sometimes even of biting harshness. There is scarcely a phrase, however insignificant, which does not make good its independent existence.[52] A searching analysis is out of the question in this place; such an analysis would serve, however, to increase our admiration of the genius which makes of strictest form the vehicle for a flow of fiery eloquence, and spreads abroad glory and beauty without stint.[53] The perfection of the art of counterpoint is not the distinguishing characteristic of this symphony alone, but of them all. The enthralling interest of the development of each movement in its necessary connection and continuity consists chiefly in the free and liberal use of the manifold resources of counterpoint. The ease and certainty of this mode of expression makes it seem fittest for what the composer has to say. Freedom of treatment penetrates every component part of the whole, producing the independent, natural motion of each. The then novel art of employing the wind instruments in separate and combined effects was especially admired by Mozart's contemporaries. His treatment of the stringed instruments showed a progress not less advanced, as, for instance, in the free treatment of the basses, as characteristic as it was melodious. The highest quality of the symphonies, however, is their harmony of tone-colour, the healthy combination of orchestral sound, which is not to be replaced by any separate effects, however charming. In this combination consists the art of making the orchestra as a living organism express the artistic idea which gives the creative impulse to the work, and controls the forces which are always ready to be set in motion. An unerring conception of the capacities for development {MOZART'S INSTRUMENTAL MUSIC.} (40) contained in each subject, of the relations of contrasting and conflicting elements, of the proportions of the parts composing the different movements,[54] and of the proportions of the movements to the whole work; finally, of the proper division and blending of the tone-colours--such are the essential conditions for the production of a work of art which is to be effective in all its parts.
