-@cindex grace notes within tuplet brackets
-
-@knownissues
-Grace notes may be placed within tuplet brackets, @emph{except}
-when a staff begins with a grace note followed by a tuplet. In this
-particular case, the grace note must be placed before the @code{\tuplet}
-command to avoid errors.

-@cindex tempo marks within tuplet brackets
-
-When using a tuplet at the beginning of a piece with a @code{\tempo}
-mark, the music must be explicitly entered in a @code{\new Voice}
-block, as discussed in @rlearning{Voices contain music}.

-The property @code{measurePosition} contains a rational number,
-which is usually positive and indicates how much of the measure
-has passed at this point. @code{\partial @var{duration}} is
-defined such that no numbered bar gets created: when used at the
-beginning of a measure, @code{measurePosition} is set to a
-negative number, implying that the current bar will be
-@emph{preceded} by additional material. When used after a measure
-has already started, however, it moves the requested distance
-before the @emph{end} of the bar.
+The @code{\partial} command is @emph{required} when the time
+signature changes in mid measure, but it may also be used alone.

The use of grace notes within voice contexts confuses the way the voice
is typeset. This can be overcome by inserting a rest or note between the
voice command and the grace note.
