 In an orchestral context, cadenzas present a special problem: when
 constructing a score that includes a cadenza, all other
 instruments should skip just as many notes as the length of the
 cadenza, otherwise they will start too soon or too late.
 
-A solution to this problem are the functions
+A 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-rest or @code{\skip}, exactly as long as the piece.  The use
-of @code{mmrest-of-length} is demonstrated in the following
