Musical propshaft. Other parts?

[GheeBhow]

Hello all,

I knocked my Traveller's propshaft while working under the car the other day, and noticed that it had a very musical resonance. In another part of my life I write music, so I recorded various bangs and scrapes along it, and I'm in the process of turning them into a virtual instrument on my computer.

Weirdly, without any tuning on my PC, the two notes A and E are a big part of the sound. They form a musical interval called a perfect fifth which is the most harmonious relationship between two notes. Other than the exhaust's trombone-like parp, are other bits of the Minor particularly musical? I might be able to build a whole track using nothing but sounds produced by my car!

When my engine is on full throttle it is music to my ears.

The Morris 1000, introduced in 1956 was, I understand, version number three of the car so, in musical terms, I suppose it could be referred to as a minor third.

Let's not forget the horn! They sometimes had two of them tuned to a pleasing interval!

I wondered was it your head you banged on the propshaft by any chance
