It would be nice to hear it ...

[@davidknizek2852]

Actually you just perfectly explained the doppler effect :D. Thank you for the video I´ve always wanted to know how tremulant works. Once when I turned it on mistakenly it very scared me XD it was shaking the whole organ...

[@richardmaryman3494]

Yes, an Austin organ...uses the 'doppler effect' to undulate the pitch. This is necessary because it is so difficult to "shake" the wind in an Austin universal chest. This is the same principle that is used in the leslie speakers for hammond organs.

Thats cool. Thats the style they put in most reed organs. I would not have thought it would have worked at a larger scale

That must be an Austin organ? I have been in chambers where they’re mounted over the tuners head, so when the person holding keys at the console turns it on, it comes around and smacks you in the head. Haha. Yes, this has happened to me. It is definitely not fun. But it is a great functional tremulant!
