My reason for believing in a fundamental emotional difference between that music and ours is of another sort. I think that in art, as in all other things, the simpler, more normal interest comes first, and the more complex, less normal, follows when the simple and normal has become, through familiarity, the insipid. While pleasure unspiced by pain is still a novelty there is no reason thus to spice it.

The question can, however, be tolerably settled by turning over the means which enable music to awaken emotion—emotion which we recognise as human, as distinguished from the mere emotion of pleasure attached to all beautiful sights and sounds. Once we have understood what these means are, we can enquire to what extent they are employed in the music of various schools and epochs, and thus judge, with some chance of likelihood, whether the music which strikes us as serene and vigorous could have affected our ancestors as turbid and enervating.
'Tis a dull enough psychological examination; but one worth making, not merely for the sake of music itself, but because music, being the most emotional of all the arts, can serve to typify the good or mischief which all art may do, according to which of our emotions it fosters.
'Tis repeating a fact in different words, not stating anything new, to say that all beautiful things awaken a specific sort of emotion, the emotion or the mood of the beautiful. Yet this statement, equivalent to saying that hot objects give us the sensation of heat, and wet objects the sensation of wetness, is well worth repeating, because we so often forget that the fact of beauty in anything is merely the fact of that thing setting up in ourselves a very specific feeling.
Now, besides this beauty or quality producing the emotion of the beautiful, there exist in things a lot of other qualities also producing emotion, each according to its kind; or rather, the beautiful thing may also be qualified in some other way, as the thing which is useful, useless, old, young, common, rare, or whatever you choose. And this coincidence of qualities produces a coincidence of states of mind. We shall experience the feeling not merely of beauty because the thing is beautiful, but also of surprise because it is startling, of familiarity because we meet it often, of attraction (independently of beauty) because the thing suits or benefits us, or of repulsion (despite the beauty) because the thing has done us a bad turn or might do us one. This is saying that beauty is only one of various relations possible between something not ourselves and our feelings, and that it is probable that other relations between them may exist at the same moment, in the same way that a woman may be a man's wife, but also his cousin, his countrywoman, his school-board representative, his landlady, and his teacher of Latin, without one qualification precluding the others.
Now, in the arts of line, colour, and projection, the arts which usually copy the appearance of objects existing outside the art, these other qualities, these other relations between ourselves and the object which exists in the relation of beauty, are largely a matter of superficial association—I mean, of association which may vary, and of which we are most often conscious.
We are reminded by the picture or statue of qualities which do not exist in it, but in its prototype in reality. A certain face will awaken disgust when seen in a picture, or reverence or amusement, besides the specific impression of beauty (or its reverse), because we have experienced disgust, awe, amusement in connection with a similar face outside the picture.
So far, therefore, as art is imitative, its non-artistic emotional capacities are due (with a very few exceptions) to association; for the feelings traceable directly to fatigue or disintegration of the perceptive faculty usually, indeed almost always, prevent the object from affecting us as beautiful. It is quite otherwise when we come to music. Here the coincidence of other emotion resides, I believe, not in the musical thing itself, not in the musician's creation without prototype in reality, resembling nothing save other musical structures; the coincidence resides in the elements out of which that structure is made, and which, for all its complexities, are still very strongly perceived by our senses. For instance, certain rhythms existing in music are identical with, or analogous to, the rhythm of our bodily movements under varying circumstances: we know alternations of long and short, variously composed regularities and irregularities of movement, fluctuations, reinforcements or subsidences, from experience other than that of music; we know them in connection with walking, jumping, dragging; with beating of heart and arteries, expansion of throat and lungs; we knew them, long before music was, as connected with energy or oppression, sickness or health, elation or depression, grief, fear, horror, or serenity and happiness. And when they become elements of a musical structure their associations come along with them. And these associations are the more powerful that, while they are rudimentary, familiar like our own being, perhaps even racial, the musical structure into which they enter is complete, individual, new: 'tis comparing the efficacy of, say, Mozart Op. So-and-so, with the efficacy of somebody sobbing or dancing in our presence.
So far for the associational power of music in awakening emotions. But music has another source of such power over us. Existing as it does in a sequence, it is able to give sensations which the arts dealing with space, and not with time, could not allow themselves, since for them a disagreeable effect could never prelude an agreeable one, but merely co-exist with it; whereas for music a disagreeable effect is effaceable by an agreeable one, and will even considerably heighten the latter by being made to precede it. Now we not merely associate fatigue or pain with any difficult perception, we actually feel it; we are aware of real discomfort whenever our senses and attention are kept too long on the stretch, or are stimulated too sharply by something unexpected. In these cases we are conscious of something which is exhausting, overpowering, unendurable if it lasted: experiences which are but too familiar in matters not musical, and, therefore, evoke the remembrance of such non-musical discomfort, which reacts to increase the discomfort produced by the music; the reverse taking place, a sense of freedom, of efficiency, of strength arising in us whenever the object of perception can be easily, though energetically, perceived. Hence intervals which the ear has difficulty in following, dissonances to which it is unaccustomed, and phrases too long or too slack for convenient scansion, produce a degree of sensuous and intellectual distress, which can be measured by the immense relief—relief as an acute satisfaction—of return to easier intervals, of consonance, and of phrases of normal rhythm and length.
