Inventions of the Tables of Sines, of Logarithms, and Algebra? I know it would ſound very odd, and perhaps a little ridiculous, and yet there’s no reaſon but the thinking our ſelves better than all the World, to hinder them from being as happy in their Diſcoveries, and as ingenious in their Inventions as we our ſelves are. [They have Muſick.] It’s the ſame with Muſick as with Geometry, it’s every where immutably the ſame, and always will be ſo. For all Harmony conſiſts in Concord, and Concord is all the World over fix’d according to the ſame invariable Meaſure and Proportion. So that in all Nations the Difference and Diſtance of Notes is the ſame, whether they be in a continued gradual Progreſſion, or the Voice makes skips over one to the next. Nay very credible Authors report, that there’s a ſort of Bird in America, that can plainly ſing in order ſix muſical Notes: Whence it follows, that the Laws of Muſick are unchangeably fix’d by Nature, and therefore the ſame Reaſon holds for their Muſick, as we e’en now ſhewed for their Geometry. For why, ſuppoſing other Nations and Creatures, endued with Reaſon and Senſe as well as we, ſhould not they reap the Pleaſures ariſing from theſe Senſes as well as we too? I don’t know what Effect this Argument, from the immutable Nature of theſe Arts, may have upon the Minds of others; I think it no inconſiderable or contemptible one, but of as great Strength as that which I made uſe of above to prove that the Planetary Inhabitants had the Senſe of Seeing. But if they take delight in Harmony, there is no doubt but that they have invented Muſical Inſtruments. For they could ſcarce help lighting upon ſome or other by chance; the Sound of a tight String, the Noiſe of the Winds, or the whiſtling of Reeds, might have given them the hint. From theſe ſmall Beginnings they perhaps, as well as we, have advanced by degrees to the Uſe of the Lute, Harp, Flute, and many ſtring’d Inſtruments. But altho’ the Tones are certain and determinate, yet we find among different Nations a quite different manner and rule for Singing; as formerly among the Dorians, Phrygians, and Lydians, and in our Time among the French, Italians, and Perſians. In like manner it may ſo happen, that the Muſick of the Inhabitants of the Planets may widely differ from all theſe, and yet be very good. But why we ſhould look upon their Muſick to be worſe than ours, there’s no reaſon can be given; neither can we well preſume that they want the Uſe of Halſ-Notes and Quarter-Notes, ſeeing the Invention of Halſ-Notes is ſo obvious, and the Uſe of them ſo agreeable to Nature. Nay, to go a Step farther, what if they ſhould excel us in the Theory and practick part of Muſick, and outdo us in Conſorts of vocal and inſtrumental Muſick, ſo artificially compos’d, that they ſhew their Skill by the Mixtures of Diſcords and Concords? and of this laſt ſort ’tis very likely the 5th and 3d are in uſe with them.
