La propiedad @code{measureLength}, junto con
@code{measurePosition}, determina cuándo es necesario dibujar una
línea divisoria.  Sin embargo, al utilizar
@code{\\scaleDurations}, el escalado proporcional de las
duraciones hace difícil introducir cambios de compás.  En este
caso se debe establecer manualmente el valor de
@code{measureLength} utilizando la función @code{ly:make-moment}.
El segundo argumento debe ser el mismo que el segundo argumento de
@code{\\scaleDurations}.

The @code{measureLength} property, together with
@code{measurePosition}, determines when a bar line is needed.  However,
when using @code{\\scaleDurations}, the scaling of durations makes it
difficult to change time signatures.  In this case,
@code{measureLength} should be set manually, using the
@code{ly:make-moment} callback.  The second argument must be the same
as the second argument of @code{\\scaleDurations}.
