This is a bit of cross over interest for me. I own a TR 6 and so enjoy the
sound of a well tuned engine, but I also play Dixieland trombone and enjoy
the sound of a well tuned band. the link below kind of combines the two.

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.
