alright this is the intro to clocks, I think it sounds 
identical to the actual song, here it is, played about two octaves above middle C 
 
  D#      D#      D#    C#     C#      C#     C#      C#     C#      C      C      C 
    A#      A#      A#    A#     A#      A#     A#      A#     A#      G#     G#     G# 
      G       G             F      F              F       F              F      F       
 
and repeat a few times
