out any regard to the quantity^Here he endeavors to fhew, how 
all the Notes come into the Scale by their Relation and Digni- 
ties; whence he thinks it will beobvious, why,for cafiners of in- 
ftruftion and convenience , the Scale of Degrees of Mufick is 
madeas Muficians now exhibit if* 
Having difpatched that^vvork, he proceeds to Mufick that 
confifts of feveral parts in Cof^firt^v^hich is made up of Harmo- 
?jy, Formality and Conformitj. Oi'^Wxch^Harmofjy is the grateful 
found produced by the jjyning of fevefal Tones in chord to 
oneanother: Formality nquhts^ that the fuccecding Notes be 
agreable to the former^ 2iX\d Conformity will, that each part have 
the Jike tendency to the fucceedi^g Notes. 
Laftly, he fpeaks ot Time or the meafures of Mufick; the due 
obfervance of which is grateful for the fame reafon given for the 
Formality of a fingle77/;?^,becaure the fubfcquent ftrokes are 
meafured by the memory of the fornier,and if they do compre- 
hend them, or are comprehended by them, it is alike plexfant ; 
the mind cannot chufe but compare one with the other,and cb- 
fcrve when the flrokes are coincident w ith the memory of the 
former. Whence it is, that, ihe lefs the intervals are, the more 
grateful is the meafure, becaufe it iseafily Scexaftly reprefent- 
ed by the memory ; v^ heteas a long fpace of rime that cannot be 
comprehended in one thoughc,is not retained in the memory in 
its exaa meafure, nor can abide the comparifon, the time paft 
being always fliortrscd by fo much as it is removed from the time 
prefenc. 
The whole is concluded by two Obfervations, by which we 
lhalllikewife conclude this Account: r.That it plainly appears 
by the Difcourfe of this Trafl,how Mufick comes to be fo copi- 
ous; for,confidering the fpecies of keys,the number of them, the 
variety of Chords,the allowable mixing of Difcord?,the diver- 
fity ofmeafure; it is not tobe wondred at, that it fhould, like 
LanguagejafFord to every Age^ every Nation, nay, every Perfon, 
particular ftiles and modes. 2. Thac it appears like wife, that 
To/tes or ^Udes of Mufick in ancient time could not be of oihtx 
kinds than are now,fince there can be no other in nature.Where- 
fore the great effefls it then had, if truly related.muft be imputed 
to the rarity of it,and the barbarity of the people, who are not 
tranfporttd with any thing after it become common to them.
