-@code{set-time-signature}, takes three arguments: the
-number of beats, the beat length, and the internal grouping of beats in
-the measure. @code{\time} and @code{set-time-signature} both apply
-to the @code{Timing} context, so they will not reset values of
-@code{beatStructure} or @code{baseMoment} that are set in
-other lower-level contexts, such as @code{Voice}.
+For this, you specify the internal grouping of beats in a measure
+as a list of numbers (in Scheme syntax) before the time signature.

+@code{\time} applies to the @code{Timing} context, so it will not
+reset values of @code{beatStructure} or @code{baseMoment} that are set
+in other lower-level contexts, such as @code{Voice}.
