[Shotimes] OT Some music maestro...

I found this in my e-mail this morning. Very cool!

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. The result is delightful. And think of the
possibilities - BMW's F1 engine, which howls all the way to
19,050rpm, could rip through the entire Hendrix songbook.
