Hinge By <M/4> x <N/4> x ...

This can be thought of as a sort of generalization of the Quarter Thru / Remake / Swing the Fractions calls, designed to get the maximum possible mileage out of them.

The call has as many parts as the fractions given. Each part is an Arm Turn by the given fraction, or, if necessary, a partner hinge followed by Arm Turns by the remaining amount.

It starts with everyone who can, or those designated by the caller. Subsequent turns are dictated by the requirement to alternate hands. That is, when you finish one part, you do the next with the person on the other side of you.

A given person may not be able to do certain parts, but each part must have some people in motion. Unlike calls like Swing the Fractions, there is no "right hand rule" other than the need to switch hands between parts.

The call is always "grand". That is, it is done in the entire setup.
