[Bell Historians] Did Harrison have a point

[Bickerton, Roderic K (SELEX) (UK)]

Urm.... handbells?

Andrew 

Glad you mentioned that.
The very big hand bells used for tune ringing vibrate so much the
movement is visible but very little sound is radiated from the
fundamental. That is because the bell is far to small a diameter,
compared to the wavelength of the lowest note being produced for it to
radiate effectively.
Harrison knew about that and produced bells with very large diameter
mouths for the weight, they do radiate.
What he had not a clue about was how to generate a large mouthed low
mass profile that could be tuned to produce a nice sounding set of
partials.
