XII. Is it not much to be lamented, that the Christians don’t use the same precaution the antients did, to prevent music from perverting the manners of youth? But we are so far from doing this, that already no music is allowed to be good, in which there is not introduced at every turn, both in the human voice, and in the instruments, points, which they call foreign, and which pass through all parts of the diapason, from the natural point to the accidental one; and this is the mode. There is no doubt but these transitions, managed with moderation, art and genius, produce an admirable effect; because they mark the expression of the words with more vivacity and spirit, than the pure diatonic progressions; and there results from so contriving things, a more delicate and expressive music. But the composers who are capable of doing this, are very few, and those few are the occasion of an infinite number of others losing and exposing themselves; who, by endeavouring to imitate them, for want of talents and address to manage the business, fail in the attempt, and form with their foreign introductions, a ridiculous music, which sometimes is insipid, and at others harsh; and when they mistake the least, there results from their labours, an unmeaning softness, and lascivious delicacy, which has no good effect on the mind, because there is no expression in it, capable of exciting any noble emotion. If, notwithstanding all that is objected to it, composers are desirous such music should go down, because it is the fashion, let them apply it to the use of the theatres and concert rooms; but don’t let them introduce it into the churches, as fashions were never contrived or calculated for them; and if the divine offices do not admit of change of modes, either in vestments or rites, why should they be admitted in musical compositions?
