These silent white keys
 were once made of elephants' teeth.
 And the chopsticks ones of ebony.
 Which is a type of wood,
 which we didn't know, 
 until Peter took lessons.
  
 The piano we now have is all plastic and chipboard
 beneath a smart black veneer, 
 black as the whole room was
 before the electricity returned just now,
 letting me make music once more.
