   7 You can have multiple time signatures occuring at the same time.
   8
   9 This is done by moving the timing engraver to staff context. Also,
  10 Staff should be given the alias @code{Timing} to make @code{\time}
  11 command work correctly. Barlines distort the regular spacing, though.
  12
  13 If the note durations do not line up, \times can be used to scale up a
  14 staff. The second staff has a 3/4 signature with a 3/5 tuplet over all
  15 of the notes. Switching off the tuplet bracket, and manually printing
  16 a 10/8 sign gives the desired effect.
