-The property @code{subdivideBeams} can be set in order to

+The beams of consecutive 16th (or shorter) notes are, by default,
+not sub-divided.  That is, the three (or more) beams stretch
+unbroken over entire groups of notes.  This behaviour can
+be modified to sub-divide the beams into sub-groups by setting 
+the property @code{subdivideBeams}.  When set, multiple beams 
+will be sub-divided at intervals defined by the current value of
+@code{beatLength} by reducing the multiple beams to just one beam
+between the sub-groups. Note that @code{beatLength} lives in the
+@code{Score} context and defaults to a quarter note.  It must be
+set to a fraction giving the duration of the beam sub-group
+using the @code{make-moment} function, as shown here:
