The property @code{measurePosition} contains a rational number
indicating how much of the measure has passed at this point. Note
that this is set to a negative number by the @code{\partial} command:
-i.e., @code{\partial 4} is internally translated to @code{-4}, meaning
+i.e., @code{\partial 4} is internally translated to @w{@code{-4}}, meaning
@qq{there is a quarter note left in the measure.}
