-The property @code{subdivideBeams} can be set in order to
-subdivide all 16th or shorter beams. When set, multiple beams
-will be sub-divided at beat positions, defined by the current
-value of @code{beatLength} (defaults to a quarter note), by
-drawing only one beam over the connection between beats.
+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:
