Other note divisions and subdivisions are possible. BORROWED DIVISIONS are possible when the division of an undotted note is applied to a dotted note (or visa versa). The result of an unnatural division is a tuplet figure: a duplet, triplet, quadruplet, etc.
The following chart demonstrates various divisions and subdivisions of dotted and undotted notes. Notice that each of the BORROWED DIVISIONS require a number to be associated with each of them. POINT (Don't click) YOUR MOUSE at the NATURAL DIVISIONS and SUBDIVISIONS of each note value and READ THE STATUS BAR message at the bottom of your window.
