we deale with Proportion, and with the 3. kinds thereof, that is Proportion Arithmeticall, Geometricall, and Musicall: You haue first to vnderstand, that of numbers some are said to be abstract, and some concreate.
The abstract are such as are not tyed to any denomination, and such are twofold, that is absolute and relatiue.
The absolute, are simply pronounced without hauing any re∣lation to any other number, measure, or quantitie, as 2. 3. 4. &c. and all numbers whatsoeuer, that are without denomination and are not attributed to any other thing.
The relatiue are those which haue relation one to another, which may be thrée manner of waies. First in respect of difference which is found by Subtraction, secondly in respect of the quotient found by Diuision, thirdly in respect of both. Of the first way springeth Arithmeticall proportion: Of the second way Geome∣tricall proportion: And of the third Musicall proportion.
