That train of thoughts and ideas which is continually passing through the mind does not always move on with, the same pace, if I may say so, or with the same order and connection. When we are gay and cheerful, its motion is brisker and more lively, our thoughts succeed one another more rapidly, and those which immediately follow one another seem frequently either to have but little connection, or to be connected rather by their opposition than by their mutual resemblance. As in this wanton and playful disposition of mind we hate to dwell long upon the same thought, so we do not much care to pursue resembling thoughts; and the variety of contrast is more agreeable to us than the sameness of resemblance. It is quite otherwise when we are melancholy and desponding; we then frequently find ourselves haunted, as it were, by some thought which we would gladly chase away, but 424 which constantly pursues us, and which admits no followers, attendants, or companions, but such as are of its own kindred and complexion. A slow succession of resembling or closely connected thoughts is the characteristic of this disposition of mind; a quick succession of thoughts, frequently contrasted and in general very slightly connected, is the characteristic of the other. What may be called the natural state of the mind, the state in which we are neither elated nor dejected, the state of sedateness, tranquillity, and composure, holds a sort of middle place between those two opposite extremes; our thoughts may succeed one another more slowly, and with a more distinct connection, than in the one; but more quickly and with a greater variety, than in the other.

Acute sounds are naturally gay, sprightly, and enlivening; grave sounds solemn, awful, and melancholy. There seems too to be some natural connection between acuteness in tune and quickness in time or succession, as well as between gravity and slowness: an acute sound seems to fly off more quickly than a grave one: the treble is more cheerful than the bass; its notes likewise commonly succeed one another more rapidly. But instrumental Music, by a proper arrangement, by a quicker or slower succession of acute and grave, of resembling and contrasted sounds, can not only accommodate itself to the gay, the sedate, or the melancholy mood; but if the mind is so far vacant as not to be disturbed by any disorderly passion, it can, at least for the moment, and to a certain degree, produce every possible modification of each of those moods or dispositions. We all readily distinguish the cheerful, the gay, and the sprightly Music, from the melancholy, the plaintive, and the affecting; and both these from what holds a sort of middle place between them, the sedate, the tranquil, and the composing. And we are all sensible that, in the natural and ordinary state of the mind, Music can, by a sort of incantation, sooth and charm us into some degree of that particular mood or disposition which accords with its own character and temper. In a concert of instrumental Music the attention is engaged, with pleasure and delight, to listen to a combination of the most agreeable and melodious sounds, which follow one another, sometimes with a quicker, and sometimes with a slower succession; and in which those that immediately follow one another sometimes exactly or nearly resemble, and sometimes contrast with one another in tune, in time, and in order of arrangement. The mind being thus successively occupied by a train of objects, of which the nature, succession, and connection correspond, sometimes to the gay, sometimes to the tranquil, and sometimes to the melancholy mood or disposition, it is itself successively led into each of those moods or dispositions; and is thus brought into a sort of harmony or concord with the Music which so agreeably engages its attention.

425 It is not, however, by imitation properly, that instrumental Music produces this effect: instrumental Music does not imitate, as vocal Music, as Painting, or as Dancing would imitate, a gay, a sedate, or a melancholy person; it does not tell us, as any of those other arts could tell us, a pleasant, a serious, or a melancholy story. It is not, as in vocal Music, in Painting, or in Dancing, by sympathy with the gaiety, the sedateness, or the melancholy and distress of some other person, that instrumental Music soothes us into each of these dispositions: it becomes itself a gay, a sedate, or a melancholy object; and the mind naturally assumes the mood or disposition which at the time corresponds to the object which engages its attention. Whatever we feel from instrumental Music is an original, and not a sympathetic feeling: it is our own gaiety, sedateness, or melancholy; not the the reflected disposition of another person.

When we follow the winding alleys of some happily situated and well laid out garden, we are presented with a succession of landscapes, which are sometimes gay, sometimes gloomy, and sometimes calm and serene; if the mind is in its natural state, it suits itself to the objects which successively present themselves, and varies in some degree its mood and present humour with every variation of the scene. It would be improper, however, to say that those scenes imitated the gay, the calm, or the melancholy mood of the mind; they may produce in their turn each of those moods, but they cannot imitate any of them. Instrumental Music, in the same manner, though it can excite all those different dispositions, cannot imitate any of them. There are no two things in nature more perfectly disparate than sound and sentiment; and it is impossible by any human power to fashion the one into any thing that bears any real resemblance to the other.

This power of exciting and varying the different moods and dispositions of the mind, which instrumental Music really possesses to a very considerable degree, has been the principal source of its reputation for those great imitative powers which have been ascribed to it. ‘Painting,’ says an author, more capable of feeling strongly than of analysing accurately, Mr. Rousseau of Geneva, ‘Painting, which presents its imitations, not to the imagination, but to the senses, and to only one of the senses, can represent nothing besides the objects of sight. Music, one might imagine, should be equally confined to those of hearing. It imitates, however, every thing, even those objects which are perceivable by sight only. By a delusion that seems almost inconceivable, it can, as it were, put the eye into the ear; and the greatest wonder, of an art which acts only by motion and succession, is, that it can imitate rest and repose. Night, Sleep, Solitude, and Silence are all within the compass of musical imitation. Though all Nature should be asleep, the person who contemplates it is awake; and the art of the musician consists in substituting, in the room of an 426 image of what is not the object of hearing, that of the movements which its presence would excite in the mind of the spectator.’—That is, of the effects which it would produce upon his mood and disposition. ‘The musician (continues the same author) will sometimes, not only agitate the waves of the sea, blow up the flames of a conflagration, make the rain fall, the rivulets flow and swell the torrents, but he will paint the horrors of a hideous desert, darken the walls of a subterraneous dungeon, calm the tempest, restore serenity and tranquillity to the air and the sky, and shed from the orchestra a new freshness over the groves and the fields. He will not directly represent any of these objects, but he will excite in the mind the same movements which it would feel from seeing them.’

Upon this very eloquent description of Mr. Rousseau I must observe, that without the accompaniment of the scenery and action of the opera, without the assistance either of the scene-painter or of the poet, or of both, the instrumental Music of the orchestra could produce none of the effects which are here ascribed to it: and we could never know, we could never even guess, which of the gay, melancholy, or tranquil objects above mentioned it meant to represent to us; or whether it meant to represent any of them, and not merely to entertain us with a concert of gay, melancholy, or tranquil Music; or, as the ancients called them, of the Diastaltic, of the Systaltic, or of the Middle Music. With that accompaniment, indeed, though it cannot always even then, perhaps, be said properly to imitate, yet by supporting the imitation of some other art, it may produce all the same effects upon us as if itself had imitated in the finest and most perfect manner. Whatever be the object or situation which the scene-painter represents upon the theatre, the Music of the orchestra, by disposing the mind to the same sort of mood and temper which it would feel from the presence of that object, or from sympathy with the person who was placed in that situation, can greatly enhance the effect of that imitation: it can accommodate itself to every diversity of scene. The melancholy of the man who, upon some great occasion, only finds himself alone in the darkness, the silence and solitude of the night, is very different from that of one who, upon a like occasion, finds himself in the midst of some dreary and inhospitable desert; and even in this situation his feelings would not be the same as if he was shut up in a subterraneous dungeon. The different degrees of precision with which the Music of the orchestra can accommodate itself to each of those diversities, must depend upon the taste, the sensibility, the fancy and imagination of the composer: it may sometimes, perhaps, contribute to this precision, that it should imitate, as well as it can, the sounds which either naturally accompany, or which might be supposed to accompany, the particular objects represented. The symphony in the French opera of Alcyone, which imitated the violence of the winds and the dashing of the waves, in the 427 tempest which was to drown Coix, is much commended by cotemporary writers. That in the opera of Isse, which imitated that murmuring in the leaves of the oaks of Dodona, which might be supposed to precede the miraculous pronunciation of the oracle: and that in the opera of Amadis, of which the dismal accents imitated the sounds which might be supposed to accompany the opening of the tomb of Ardari, before the apparition of the ghost of that warrior, are still more celebrated. Instrumental Music, however, without violating too much its own melody and harmony, can imitate but imperfectly the sounds of natural objects, of which the greater part have neither melody nor harmony. Great reserve, great discretion, and a very nice discernment are requisite, in order to introduce with propriety such imperfect imitations, either into Poetry or Music; when repeated too often, when continued too long, they appear to be what they really are, mere tricks, in which a very inferior artist, if he will only give himself the trouble to attend to them, can easily equal the greatest. I have seen a Latin translation of Mr. Pope’s Ode on St. Cecilia’s Day, which in this respect very much excelled the original. Such imitations are still easier in Music. Both in the one art and in the other, the difficulty is not in making them as well as they are capable of being made, but in knowing when and how far to make them at all: but to be able to accommodate the temper and character of the Music to every peculiarity of the scene and situation with such exact precision, that the one shall produce the very same effect upon the mind as the other, is not one of those tricks in which an inferior artist can easily equal the greatest; it is an art which requires all the judgment, knowledge, and invention of the most consummate master. It is upon this art, and not upon its imperfect imitation, either of real or imaginary sounds, that the great effects of instrumental Music depend; such imitations ought perhaps to be admitted only so far as they may sometimes contribute to ascertain the meaning, and thereby to enhance the effects of this art.

By endeavouring to extend the effects of scenery beyond what the nature of the thing will admit of, it has been much abused; and in the common, as well as in the musical drama, many imitations have been attempted, which, after the first and second time we have seen them, necessarily appear ridiculous: such are, the Thunder rumbling from the Mustard-bowl, and the Snow of Paper and thick Hail of Pease, so finely exposed by Mr. Pope. Such imitations resemble those of painted Statuary; they may surprise at first, but they disgust ever after, and appear evidently such simple and easy tricks as are fit only for the amusement of children and their nurses at a puppet-show. The thunder of either theatre ought certainly never to be louder than that which the orchestra is capable of producing; and their most dreadful tempests ought never to exceed what the scene painter is capable of representing. In such imitations there may be an art which merits 428 some degree of esteem and admiration. In the other there can be none which merits any.

This abuse of scenery has both subsisted much longer, and been carried to a much greater degree of extravagance, in the musical than in the common drama. In France it has been long banished from the latter; but it still continues, not only to be tolerated, but to be admired and applauded in the former. In the French operas, not only thunder and lightning, storms and tempests, are commonly represented in the ridiculous manner above mentioned, but all the marvellous, all the supernatural of Epic Poetry, all the metamorphoses of Mythology, all the wonders of Witchcraft and Magic, every thing that is most unfit to be represented upon the stage, are every day exhibited with the most complete approbation and applause of that ingenious nation. The music of the orchestra producing upon the audience nearly the same effect which a better and more artful imitation would produce, hinders them from feeling, at least in its full force, the ridicule of those childish and awkward imitations which necessarily abound in that extravagant scenery. And in reality such imitations, though no doubt ridiculous every where, yet certainly appear somewhat less so in the musical than they would in the common drama. The Italian opera, before it was reformed by Apostolo, Zeno, and Metastasio, was in this respect equally extravagant, and was upon that account the subject of the agreeable raillery of Mr. Addison in several different papers of the Spectator. Even since that reformation it still continues to be a rule, that the scene should change at least with every act; and the unity of place never was a more sacred law in the common drama, than the violation of it has become in the musical: the latter seems in reality to require both a more picturesque and a more varied scenery, than is at all necessary for the former. In an opera, as the Music supports the effect of the scenery, so the scenery often serves to determine the character, and to explain the meaning of the Music; it ought to vary therefore as that character varies. The pleasure of an opera, besides, is in its nature more a sensual pleasure, than that of a common comedy or tragedy; the latter produce their effect principally by means of the imagination: in the closet, accordingly, their effect is not much inferior to what it is upon the stage. But the effect of an opera is seldom very great in the closet; it addresses itself more to the external senses, and as it soothes the ear by its melody and harmony, so we feel that it ought to dazzle the eye with the splendour of its scenery.

In an opera the instrumental Music of the orchestra supports the imitation both of the poet and of the actor, as well as of the scene-painter. The overture disposes the mind to that mood which fits it for the opening of the piece. The Music between the acts keeps up the impression which the foregoing had made, and prepares us for that which the following is to make. When the orchestra interrupts, as it 429 frequently does, either the recitative or the air, it is in order either to enforce the effect of what had gone before, or to put the mind in the mood which fits it for hearing what is to come after. Both in the recitatives and in the airs it accompanies and directs the voice, and often brings it back to the proper tone and modulation, when it is upon the point of wandering away from them; and the correctness of the best vocal Music is owing in a great measure to the guidance of instrumental; though in all these cases it supports the imitation of another art, yet in all of them it may be said rather to diminish than to increase the resemblance between the imitating and the imitated object. Nothing can be more unlike to what really passes in the world, than that persons engaged in the most interesting situations, both of public and private life, in sorrow, in disappointment, in distress, in despair, should, in all that they say and do, be constantly accompanied with a fine concert of instrumental Music. Were we to reflect upon it, such accompaniment must in all cases diminish the probability of the action, and render the representation still less like nature than it otherwise would be. It is not by imitation, therefore, that instrumental Music supports and enforces the imitations of the other arts; but it is by producing upon the mind, in consequence of other powers, the same sort of effect which the most exact imitation of nature, which the most perfect observation of probability, could produce. To produce this effect is, in such entertainments, the sole end and purpose of that imitation and observation. If it can be equally well produced by other means, this end and purpose may be equally well answered.

But if instrumental Music can seldom be said to be properly imitative, even when it is employed to support the imitation of some other art, it is commonly still less so when it is employed alone. Why should it embarrass its melody and harmony, or constrain its time and measure, by attempting an imitation which, without the accompaniment of some other art to explain and interpret its meaning, nobody is likely to understand? In the most approved instrumental Music, accordingly, in the overtures of Handel and the concertos of Correlli, there is little or no imitation, and where there is any, it is the source of but a very small part of the merit of those compositions. Without any imitation, instrumental Music can produce very considerable effects; though its powers over the heart and affections are, no doubt, much inferior to those of vocal Music, it has, however, considerable powers: by the sweetness of its sounds it awakens agreeably, and calls upon the attention; by their connection and affinity it naturally detains that attention, which follows easily a series of agreeable sounds, which have all a certain relation both to a common, fundamental, or leading note, called the key note; and to a certain succession or combination of notes, called the song or composition. By means of this relation each foregoing sound seems to introduce, and as it were prepare the mind for the following: by its 430 rhythmus, by its time and measure, it disposes that succession of sounds into a certain arrangement, which renders the whole more easy to be comprehended and remembered. Time and measure are to instrumental Music what order and method are to discourse; they break it into proper parts and divisions, by which we are enabled both to remember better what is gone before, and frequently to foresee somewhat of what is to come after; we frequently foresee the return of a period which we know must correspond to another which we remember to have gone before; and, according to the saying of an ancient philosopher and musician, the enjoyment of Music arises partly from memory and partly from foresight. When the measure, after having been continued so long as to satisfy us, changes to another, that variety, which thus disappoints, becomes more agreeable to us than the uniformity which would have gratified our expectation: but without this order and method we could remember very little of what had gone before, and we could foresee still less of what was to come after; and the whole enjoyment of Music would be equal to little more than the effect of the particular sounds which rung in our ears at every particular instant. By means of this order and method it is, during the progress of the entertainment, equal to the effect of all that we remember, and of all that we foresee; and at the conclusion of the entertainment, to the combined and accumulated effect of all the different parts of which the whole was composed.
