10 minutes and 24 seconds.

 

                                                                           A medical song for you..

                                                   Answer is  hidden inside..

                                              My timpani play a rhythmic song,
                                              With hammer on anvil I play along.
                                              Down my canal no ship sets course,
                                               And I have a stirrup that fits no horse.
                                                                  What am I?
