-A solution to this problem is to use the functions
+One solution to this problem is to use the functions
@code{mmrest-of-length} and @code{skip-of-length}. These Scheme
-functions take a piece of music as argument, and generate a multi-measure
-rest or @code{\skip}, exactly as long as the piece. The use of
-@code{mmrest-of-length} is demonstrated in the following example.
+functions take a defined piece of music as an argument and generate a
+multi-measure rest or @code{\skip} exactly as long as the piece.
