Load the link and press play. 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

Cheers,
Lawrence
