F1 engine playing "When The Saints Go Marching In"
This is a 50-second audio clip. The first 25 seconds are a 750 horsepower engine revving up. Then the song begins. The magazine F1 Racing explains:

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.
