   9 This example shows how to put crosses on stems. Mark the beginning
  10 of a spoken section with the @code{\\speakOn} keyword, and end it
  11 with the @code{\\speakOff} keyword.  Remember to end cross sections
  12 before entering any rest: this function also adds crosses to the
  13 invisible stems of rests.
