Sembra d’alberi densi alta foresta
L’ un campo, e l’ altro; di tant’ aste abbonda.
Son tesi gli archi, e son le lance in resta:
Vibransi i dardi, e rotasi ogni fionda.
Ogni cavallo in guerra anco s’ appresta:
Gli odii, e’l furor del suo signor seconda:
Raspa, batte, nitrisce, e si raggira,
Gonfia le nari; e fumo, e fuoco spira.

Bello in sì bella vista anco è l’orrore:
E di mezzo la tema esce il diletto.
Ne men le trombe orribili, e canore
Sono a gli orecchi lieto, e fero oggetto.
Pur il campo fedel, benchè minore,
Par di suon più mirabile, e d’aspetto.
E canta in più guerriero, e chiaro carme
Ogni sua tromba, e maggior luce han l’arme.
Gerusalemme liberata, cant. 20. st. 29. & 30.

A virtuous man has drawn on himself a great misfortune, by a fault incident to human nature, and therefore venial. The remorse he feels aggravates his distress, and consequently raises our pity to a high pitch. We indeed blame the man; and the indignation raised by the fault he has committed, is dissimilar to pity. These two passions however proceeding from different views of the same object, are forced into a sort of union. But the indignation is so slight as scarce to be felt in the mixture with pity. Subjects of this kind, are of all the fittest for tragedy. But of this afterward[38].

Opposite emotions are so dissimilar as not to admit any sort of union, even where they proceed from causes the most intimately connected. Love to a mistress, and resentment for her infidelity, are of this nature. They cannot exist otherwise than in succession, which by the connection of their causes is commonly rapid. And these emotions will govern alternately, till one of them obtain the ascendent, or both be obliterated. A succession opens to me by the death of a worthy man, who was my friend as well as my kinsman. When I think of my friend I am grieved; but the succession gives me joy. These two causes are intimately connected, for the succession is the direct consequence of my friend’s death. The emotions however being opposite, do not mix: they prevail alternately, perhaps for a course of time, till grief for my friend’s death be banished by the pleasures of opulence. A virtuous man suffering unjustly, is an example of the same kind. I pity him, and I have great indignation at the author of the wrong. These emotions proceed from causes nearly connected; but being directed upon different objects, they are not forced into union. The opposition preserves them distinct; and accordingly they are found to govern alternately, the one sometimes prevailing and sometimes the other.

Next of dissimilar emotions arising from unconnected causes. Good and bad news of equal importance arriving at the same instant from different quarters, produce opposite emotions, the discordance of which is not felt because they are not forced into union. They govern alternately, commonly in a quick succession, till their force be spent. In the same manner, good news arriving to a man labouring under distress, occasions a vibration in his mind from the one to the other.

Osmyn. By heav’n thou’st rous’d me from my lethargy.
The spirit which was deaf to my own wrongs,
And the loud cries of my dead father’s blood,
Deaf to revenge—nay, which refus’d to hear
The piercing sighs and murmurs of my love
Yet unenjoy’d; what not Almeria could
Revive, or raise, my people’s voice has waken’d.
O my Antonio, I am all on fire,
My soul is up in arms, ready to charge
And bear amidst the foe with conqu’ring troops.
I hear ’em call to lead ’em on to liberty,
To victory; their shouts and clamours rend
My ears, and reach the heav’ns: where is the king?
Where is Alphonso? ha! where! where indeed?
O I could tear and burst the strings of life,
To break these chains. Off, off, ye stains of royalty!
Off, slavery! O curse, that I alone
Can beat and flutter in my cage, when I
Would soar and stoop at victory beneath!
Mourning Bride, act 3. sc. 2.

If the emotions be unequal in force, the stronger after a conflict will extinguish the weaker. Thus the loss of a house by fire or of a sum of money by bankruptcy, will make no figure in opposition to the birth of a long-expected son, who is to inherit an opulent fortune. After some slight vibrations, the mind settles in joy, and the loss is forgot.

The foregoing observations, will be found of great use in the fine arts. Many practical rules are derived from them, which I shall have occasion afterward to mention. For instant satisfaction in part, I propose to show the use of these observations in music, a theme I insist upon at present, not being certain of another opportunity more favourable. It will be admitted, that no combination of sounds but what is agreeable to the ear, is intitled to the name of music. Melody and harmony are separately agreeable and in union delightful. The agreeableness of vocal music differs from that of instrumental. The former being intended to accompany words, ought to be expressive of the sentiment that is conveyed by the words. But the latter having no connection with words, may be agreeable without expressing any sentiment. Harmony properly so called, though delightful when in perfection, is not expressive of sentiment; and we often find good melody without the least tincture of it.

These preliminaries being established, I proceed directly to the point. In vocal music, the intimate connection of sense and sound rejects dissimilar emotions, those especially that are opposite. Similar emotions produced by the sense and sound go naturally into union; and at the same time are felt to be concordant or harmonious. Dissimilar emotions, on the other hand, forced into union by causes intimately connected, not only obscure each other, but are also unpleasant by discordance. From these principles it is easy to say what sort of poetical compositions are fitted for music. It is evident that no poem expressing the sentiments of any disagreeable passion is proper. The pain a man feels who is actuated with malice or unjust revenge, disqualifies him for relishing music or any thing that is entertaining. And supposing him disposed, against nature, to vent his sentiments in music, the mixture would be unpleasant; for these passions raise disgust and aversion in the audience[39], a tone of mind opposite to every emotion that music can inspire. A man seized with remorse cannot bear music, because every sort of it must be discordant with his tone of mind; and when these by an unskilful artist are forced into union, the mixture is unpleasant to the audience.

In general, music never can have a good effect in conjunction with any composition expressive of malice, envy, peevishness, or any other dissocial passion. The pleasure of music, on the other hand, is similar to all pleasant emotions; and music is finely qualified for every song where such emotions are expressed. Music particularly in a chearful tone, is concordant in the highest degree with every emotion in the same tone; and hence our taste for chearful airs expressive of mirth and jollity. Music is peculiarly well qualified for accompanying every sympathetic emotion. Sympathetic joy associates finely with chearful music, and sympathetic pain not less finely with music that is tender and melancholy. All the different emotions of love, viz. tenderness, concern, anxiety, pain of absence, hope, fear, &c. accord delightfully with music. A person in love, even when unkindly treated, is soothed by music. The tenderness of love still prevailing, accords with a melancholy strain. This is finely exemplified by Shakespear in the fourth act of Othello, where Desdemona calls for a song expressive of her distress. Wonderful is the delicacy of that writer’s taste, which fails him not even in the most refined emotions of human nature. Melancholy music again is suitable to slight grief, which requires or admits consolation. But deep grief, which refuses all consolation, rejects for that reason even melancholy music. For a different reason, music is improper for accompanying pleasant emotions of the more important kind. These totally ingross the mind, and leave no place for music or any sort of amusement. In a perilous enterprise to dethrone a tyrant, music would be impertinent, even where hope prevails, and the prospect of success is great. Alexander attacking the Indian town and mounting the wall, had certainly no impulse to exert his prowess in a song. It is true, that not the least regard is paid to these rules either in the French or Italian opera; and the attachment we have to these compositions, may at first sight be considered as a proof that the foregoing doctrine cannot be founded on human nature. But the general taste for operas is at bottom no authority against me. In our operas the passions are so imperfectly expressed, as to leave the mind free for relishing music of any sort indifferently. It cannot be disguised, that the pleasure of an opera is derived chiefly from the music, and scarce at all from the sentiments. A happy coincidence of emotions raised by the song and by the music, is extremely rare; and I venture to affirm, that there is no example of it unless where the emotion raised by the former is pleasant as well as that raised by the latter.
