An Australian ensemble has "rediscovered" the sound of the bells that play a big part in Mozart's "Magic Flute"--a sound which, it's claimed, has been lost for generations.
How to be certain that this is the same sound that Mozart knew? .... Well, I suspect there's a lot more scholarly research behind this than this article can go into. Meanwhile this instrument is fun to hear and to look at (check out the slide show and audio).
Enuff!! Enough scholarly research into what Mozart actually had in mind. In the ensuing two-hundred and more years, practical minded performers have continuously evolved what they believe "works" musically and theatrically in a contemporary world. This continuous evolution ought to count for as much as whatever scholars think Mozart had in mind, be it the bells in the "Magic Flute," or the voguish preference for vibratoless sopranos and wispy violin players. The scholars may be wrong after all, and how would we know?
