> 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

> various rev/note ranges in the correct sequence
