Don't know, but it's really wussy! We have a big car (estate) and you'd think it would have a meaty horn, but no. Like an angels' fart is this horn. I make more noise yelling out the window! My car was a Lada Estate and honked in Eb. I think Fords are F, Nissan are G or G#.

As far as I can tell, I've never farted in A.
