Of Prolation.
WHerefore Prolation is the essentiall quantitie of Semibreefes: or it is the setting of two or three Minims against one Semibreefe. And it is twofold, to wit the greater, (which is a Semibreefe measured by three Minims, or the comprehending of three Minims in one Semibreefe, whose signe is a point inclosed in a signe thus, 〈☐☐〉〈☐☐〉) The lesser Prolation is a Semibreefe mea∣sured with two Minims onely, whose signe is the absence of a pricke. For Franchinus saith, They carry with them the imperfecting of the figure, when the signes are wanting, thus: 〈♫〉〈♫〉 Time perfect. Imperf. time. Greater Prol. Lesse Prolation.
There was one well seen in this Art, that made this vnderwritten Example of these three degrees, reasonable learnedly and compendiously for the help of yong beginners: which (by his fauour) wee will not thinke vnwor∣thy to set downe here. 〈♫〉〈♫〉 The Tenor, in the lesser Moode perfect. The Descant, in the greater Prolation. 〈♫〉〈♫〉 The Base, in time perfect.
