+There are two types of beaming rules: @emph{beam-grouping}
+rules and @emph{beam-ending} rules. Beam-grouping rules are the
+simplest, but are over-ridden by any beam-ending rules which apply.
-In normal time signatures, automatic beams can start on any note
-but can end in only a few positions within the measure: beams can
-end on a beat, or at durations specified by the properties in
-@code{autoBeamSettings}. The properties in
-@code{autoBeamSettings} consist of a list of rules for where beams
-can begin and end. The default @code{autoBeamSettings} rules are
-defined in @file{scm/@/auto@/-beam@/.scm}.
+The placement of automatic beams is determined by applying the
+following rules in order:
+
+@itemize
+
+@item If a manual beam is specified with @code{[..]} set the beam
+as specified, otherwise
+
+@item if @code{\autoBeamOff} is in force do not beam, otherwise
+
+@item if a beam-ending rule applies use it to determine the valid
+places where beams may end, otherwise
+
+@item if a valid (see below) beat-grouping rule applies use it to
+group notes with beams, otherwise
+
+@item use the value of @code{beatLength} to group notes with beams
+
+@end itemize
+
+@i{@strong{Modifying the grouping of beats}}
+
+If there are no beam-ending rules defined for the beam duration of a
+particular beam in the time signature in use, its beaming is
+controlled by three context properties: @code{measureLength},
+@code{beatLength} and @code{beatGrouping}. These properties may be
+set in the @code{Score}, @code{Staff} or @code{Voice} contexts to
+delimit their scope. The default values are set while processing
+@code{\time} commands, so any @code{\set} commands to modify their
+value must be placed after all @code{\time} commands.
+
+@warning{These three properties become effective for a particular
+beam @strong{only} if there are no beam-ending rules predefined for
+that beam's duration in the time signature in use, or if these
+beam-ending rules have all been reverted.}
+
+These determine the beaming as follows:
+
+Beams may begin anywhere (unless a beam is already active). Beams
+end at a time determined by the values of @code{beatGrouping} and
+@code{beatLength}, as follows:
+
+@itemize
+
+@item If @code{beatGrouping} and @code{beatLength} are consistent
+with @code{measureLength}, @code{beatGrouping} is used to determine
+the end points of beams.
+
+@item If @code{beatGrouping} and @code{beatLength} are inconsistent
+with @code{measureLength}, @code{beatLength} is used to determine
+the end points of beams.
+
+@end itemize
+
+By default the @code{measureLength} and @code{beatLength} are
+derived from the time signature set by the @code{\time} command.
+The @code{measureLength} is set to be exactly the same length as
+the measure length given by the time signature, and the
+@code{beatLength} is set to be the same as one over the denominator
+of the time signature.
+
+The default value of @code{beatGrouping} is taken from a table in
+@file{scm/@/music@/-functions@/.scm}. To find this, see
+@rlearning{Other sources of information}. It defines the beat
+grouping for 3/8, 4/8, 5/8, 8/8, and all the common compound time
+signatures.
+
+Both @code{measureLength} and @code{beatLength} are @i{moments},
+units of musical duration. A quantity of type @i{moment} is
+created by the scheme function @code{ly:make-moment}. For more
+information about this function, see @ref{Time administration}.
+
+@code{beatGrouping} is a list of integers giving the number of
+beats in each group.

+@strong{@i{Modifying the beam end points}}
+
+Beam-ending rules are required when beams of different durations are
+to end at different points within the measure. For example, it may
+be desirable for eighth-note beams in 4/4 time to end only at the
+end of the measure or half-way through it, but for sixteenth-note
+beams to end at quarter note positions to avoid overly long beamed
+runs. The rules work as follows:
+
+Automatic beams can start on any note but can end at only a few
+positions within the measure, namely at positions specified by the
+properties in @code{autoBeamSettings}. These properties consist of
+a list of rules defining where beams can end. The default
+@code{autoBeamSettings} rules are defined in
+@file{scm/@/auto@/-beam@/.scm}. To find this file, see
+@rlearning{Other sources of information}.
In order to add a rule to the list, use
+
@example

If you want to end a note with a grace, use the @code{\afterGrace}
command. It takes two arguments: the main note, and the grace
notes following the main note.
This will put the grace notes after a space lasting 3/4 of the
length of the main note. The default fraction 3/4 can be changed by
setting @code{afterGraceFraction}. The following example shows
