Now the nature of man consists in this, that his will strives, is satisfied and strives anew, and so on for ever. Indeed, his happiness and well-being consist simply in the quick transition from wish to satisfaction, and from satisfaction to a new wish. For the absence of satisfaction is suffering, the empty longing for a new wish, languor, _ennui_. And corresponding to this the nature of melody is a constant digression and deviation from the key-note in a thousand ways, not only to the harmonious intervals to the third and dominant, but to every tone, to the dissonant sevenths and to the superfluous degrees; yet there always follows a constant return to the key-note. In all these deviations melody expresses the multifarious efforts of will, but always its satisfaction also by the final return to an harmonious interval, and still more, to the key-note. The composition of melody, the disclosure in it of all the deepest secrets of human willing and feeling, is the work of genius, whose action, which is more apparent here than anywhere else, lies far from all reflection and conscious intention, and may be called an inspiration. The conception is here, as everywhere in art, unfruitful. The composer reveals the inner nature of the world, and expresses the deepest wisdom in a language which his reason does not understand; as a person under the influence of mesmerism tells things of which he has no conception when he awakes. Therefore in the composer, more than in any other artist, the man is entirely separated and distinct from the artist. Even in the explanation of this wonderful art, the concept shows its poverty and limitation. I shall try, however, to complete our analogy. As quick transition from wish to satisfaction, and from satisfaction to a new wish, is happiness and well-being, so quick melodies without great deviations are cheerful; slow melodies, striking painful discords, and only winding back through many bars to the keynote are, as analogous to the delayed and hardly won satisfaction, sad. The delay of the new excitement of will, languor, could have no other expression than the sustained keynote, the effect of which would soon be unbearable; very monotonous and unmeaning melodies approach this effect. The short intelligible subjects of quick dance-music seem to speak only of easily attained common pleasure. On the other hand, the _Allegro maestoso_, in elaborate movements, long passages, and wide deviations, signifies a greater, nobler effort towards a more distant end, and its final attainment. The _Adagio_ speaks of the pain of a great and noble effort which despises all trifling happiness. But how wonderful is the effect of the _minor_ and _major_! How astounding that the change of half a tone, the entrance of a minor third instead of a major, at once and inevitably forces upon us an anxious painful feeling, from which again we are just as instantaneously delivered by the major.
