violent motion of the primum mobile, is the most swift, and acute sound of all; but the violent motion of the Moon is most slow and heavy, which proportion and reciprocation of motions yeelds a most pleasant Harmony; from hence there are not any songs, sounds, or musicall instruments more powerfull in moving mans affections, or introducing magicall impressions, then those which are composed of numbers, measures, and proportions, after the example of the Heavens. Also the Harmony of the Elements is drawn forth from their BAses, and Angles, of which we have spoken before; for between Fire and Aire, there is a double proportion in the Bases, and one and an half in solid Angles; again in Planes, a double; there ariseth hence an Harmony of a double Diapason, and a Diapente. Betwixt the Aire and Water, the proportion in their Bases is double, and one and an half; hence Dipason, and Diapente; but in their Angles double; Hence again Diapason; but between Water and Earth the proportion in the Bases, is threefold and a third part more; from hence ariseth Diapason, Diapente, Diatessaron; but in the Angles one and an half, again constituting Diapente. To conclude, betwixt Earth and Fire, in the Bases the proportion is one and an half, making Diapente; but in the Angles, double, causing Diapason; but between Fire, and Water, Aire and Earth, there is scarce any consonancy, because they have a perfect contrariety in their qualities, but they are united by the imtermediate Element. <
