-Tuplets are made from a music expression by multiplying all the

+Tuplets are made from a music expression with the @code{\tuplet}
+command, multiplying the speed of the music expression by a
+fraction:
@example
-\times @var{fraction} @{ @var{music} @}
+\tuplet @var{fraction} @{ @var{music} @}
@end example
@noindent
-The duration of @code{@var{music}} will be multiplied by the
-fraction. The fraction's denominator will be printed over or
+The fraction's numerator will be printed over or
under the notes, optionally with a bracket. The most common
-tuplet is the triplet in which 3 notes have the duration of 2, so
-the notes are 2/3 of their written length.
+tuplets are triplets: 3@tie{}notes sound within the duration
+normally allowed for@tie{}2:
@lilypond[quote,verbatim,relative=2]
-a2 \times 2/3 { b4 b b }
-c4 c \times 2/3 { b4 a g }

+@cindex tuplet grouping
+@noindent
+When entering long passages of tuplets, having to write a separate
+@code{\tuplet} command for each group is inconvenient. It is
+possible to specify the duration of one tuplet group directly
+before the music in order to have the tuplets grouped
+automatically:

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{\times}
+particular case, the grace note must be placed before the @code{\tuplet}

+The calculation of the position within a measure must take into
+account all the scaling factors applied to the notes within that
+measure and any fractional carry-out from earlier measures. This
+calculation is carried out using rational numbers. If an intermediate
+numerator or denominator in that calculation exceeds 2^30 the

-A tie is entered using the tilde symbol (@code{~}).
+A tie is entered by appending a tilde symbol (@code{~}) to the first
