When music imitates the modulations of grief or joy, it either actually inspires us with those passions, or at least puts us in the mood which disposes us to conceive them. But when it imitates the notes of anger, it inspires us with fear. Joy, grief, love, admiration, devotion, are all of them passions which are naturally musical. Their natural tones are all soft, clear, and melodious; and they naturally express themselves in periods which are distinguished by regular pauses, and which upon that account are easily adapted to the regular returns of the correspondent airs of a tune. The voice of anger, on the contrary, and of all the passions which are akin to it, is harsh and discordant. Its periods too are all irregular, sometimes very long, and sometimes very short, and distinguished by no regular pauses. It is with difficulty therefore, that music can imitate any of those passions; and the music which does imitate them is not the most agreeable. A whole entertainment may consist, without any impropriety, of the imitation of the social and agreeable passions. It would be a strange entertainment which consisted altogether of the imitations of hatred and resentment.
If those passions are disagreeable to the spectator, they are not less so to the person who feels them. Hatred and anger are the greatest poison to the happiness of a good mind. There is, in the very feeling of those passions, something harsh, jarring, and convulsive, something that tears and distracts the breast, and is altogether destructive of that composure and tranquillity of mind which is so necessary to happiness, and which is best promoted by the contrary passions of gratitude and love. It is not the value of what they lose by the perfidy and ingratitude of those they live with, which the generous and humane are most apt to regret. Whatever they may have lost, they can generally be very happy without it. What most disturbs them is the idea of perfidy and ingratitude exercised towards themselves; and the discordant and disagreeable passions which this excites, constitute, in their own opinion, the chief part of the injury which they suffer.
How many things are requisite to render the gratification of resentment completely agreeable, and to make the spectator thoroughly sympathize with our revenge? The provocation must first of all be such that we should become contemptible, and be exposed to perpetual insults, if we did not, in some measure, resent it. Smaller offences are always better neglected; nor is there anything more despicable than that froward and captious humour which takes fire upon every slight occasion of quarrel. We should resent more from a sense of the propriety of resentment, from a sense, that mankind expect and require it of us, than because we feel in ourselves the furies of that disagreeable passion. There is no passion, of which the human mind is capable, concerning whose justness we ought to be so doubtful, concerning whose indulgence we ought so carefully to consult our natural sense of propriety, or so diligently to consider what will be the sentiments of the cool and impartial spectator. Magnanimity, or a regard to maintain our own rank and dignity in society, is the only motive which can ennoble the expressions of this disagreeable passion. This motive must characterize our whole style and deportment. These must be plain, open, and direct; determined without positiveness, and elevated without insolence; not only free from petulance and low scurrility, but generous, candid, and full of all proper regards, even for the person who has offended us. It must appear, in short, from our whole manner, without our labouring affectedly to express it, that passion has not extinguished our humanity; and that if we yield to the dictates of revenge, it is with reluctance, from necessity, and in consequence of great and repeated provocations. When resentment is guarded and qualified in this manner, it may be admitted to be even generous and noble.

Of the Social Passions
As it is a divided sympathy which renders the whole set
