I’ve heard that, too, but it’s never ever really do a many sense come me. Something that only produces a single note can’t be in the key of ANYTHING. It’s not like your vehicle horn is going come play a track (those third-party contraptions the everyone had actually hooked as much as their dare for 2 weeks in 1983 the played things favor the Dukes the Hazzard fanfare notwithstanding).

I’ve heard that, too, but it’s never really made a the majority of sense come me. Miscellaneous that only produces a single note can’t be in the crucial of ANYTHING.

I have actually heard in the past that most vehicle horns create an F or F#.

According come this site, and also who knows if that true…

Up until the mid 1960’s most American vehicle horns to be tuned to the musical notes of E flat or C. Due to the fact that then, plenty of manufacturers have actually moved increase on the scale to note F sharp and also A sharp.


Aha! That’s whereby the misunderstanding was (on my part, naturally)! Every time i’ve heard this “factoid” that was the the horns to be in the vital of F, not that they created the note “F”.


60’s and also 70’s era cars had actually 2 horns that sounded simultaneously. We used to make fun of those tiny tiny foreign cars the went meep meep with just one horn. That course, now every vehicle goes meep meep with just one horn, but really old cars provided to do a chord. Kind of.

My kit automobile has an aaoogah horn. Ns don’t recognize what crucial you deserve to say “aaooogah” is in.


In the 60s and also 70s all general Motors (Chevy, Olds, Pontiac, Cadillac, and GMC) horns were made in ~ Delco Remy here in Anderson. The lower priced cars had actually two notes, the fancier ones had actually three, and also the Cadillacs had actually a chord they called the Klaxon Quartet. An old friend was a horn engineer, and also he said me it to be a diminished seventh, something you might hear in Barbershop Quartet music. Currently you know practically everything ns know about car horns.

On the old DR horns, there to be a tiny adjustment screw that was provided to tune the horn on the assembly line. It i will not ~ tweak the note very much, but if you fiddled with it, you can make your horns a little more irritating to a listener v a great pitch sense.

If ns remember correctly, the 2 horns were piched a half-tone apart. The dissonance would gather more attention native the honkee.


Chord schmord.

Some fellow railfans top top a railway blog post board i visit actually bought a surplus “five chime” horn from a diesel-electric locomotive, and mounted it ~ above the roof of your pickup truck. They have an wait cylinder in the tray of the van to drive the horn. When they avoid for fuel, they simply top up the air through the tire pump.
