Strange engine sounds

According to Tim Blair in Oz, the Asiatech folks have programmed
their F-1 engine to play music. I quote:
First you'll hear a 10-cylinder, 750 horsepower Asiatech F1 engine being warmed up. Then it performs a rousing version of "When The Saints Come Marching In", to the delight of assembled pit staff and journalists.
Here's how the magic was achieved (technical/musical details via F1 Racing magazine):
As we all know, a V10 engine produces five combustions per
revolution at a frequency per second of 60/(5 x revs per minute),
which equals 12/rpm. Therefore, to work out the revs you need to hit a particular musical note, you multiply the note's frequency by 12. To play a 440Hz 'A', for example, you need 5,280rpm. For 'C', use 3,139rpm, for 'F' 4,191rpm, and so on.
Asiatech's French technicians (the engine, despite its name, is
derived from a Peugeot design) simply programmed their engine to run through the various rev/note ranges in the correct sequence.
