G&J cast many peals of eight and ten, but only five complete peals of twelve. This paper investigates these peals to see what conclusions can be reached about how they were designed and tuned. […]

Weights, sizes and frequencies
Finding ways to relate the weight, size (generally mouth diameter) and nominal frequency of bells is useful, because it allows values to be estimated what data is not available. Some work on this was done by André Lehr, as reported in his 1986 paper. Other models have been developed and refined since by bellfounders and […]
Scale of thickness of bells
An investigation into the scale of thickness of 7,653 bells and how it affects prime and octave nominal tuning […]
Bell weights, sizes and frequencies
Bell weights, diameters and frequencies are obviously related; heavier bells sound a deeper note, and heavier bells are generally bigger in diameter. But are there any quantitative rules that allow, say, a bell’s weight to be estimated from its diameter and partial frequencies? Partial tones and bell diameters are generally easy to measure or are […]
