Rust and the sound of steel bells

In my article written last year on the acoustics of steel bells, I suggested that although it is often said that rust affects the tone of steel bells, in practice this seems not to be the case. I have observed that Bochumer steel bells of the 1950s and 1960s have true-harmonic partials when measured today, presumably little […]

Steel bells in Britain and Germany

This article was first published in The Ringing World, issue 5523, March 3 2017, page 196, and revised January 2023. In November 2015, I sang in a concert in the Gustav Adolphus Memorial Church in Nuremburg. During the concert, the 3.4 tonne steel tenor rang the curfew, a lovely and captivating sound. The experience inspired […]

Steel, tubular and hemispherical bells

Steel bells Bells are normally cast in an alloy of copper and tin. In the second half of the 19th century, almost 1,000 cast steel bells were produced by Naylor Vickers in Sheffield. These bells have a reputation for poor sound. But in Germany, Bochumer Verein cast huge quantities of steel bells, and from the […]

Lehr’s paper on the theory of bell tuning

This paper, published in translation in Rossing’s book Acoustics of Bells is of interest for a number of reasons. Most importantly, it explains the physical processes involved in bell tuning and in particular where on the inside of the bell the tuner removes metal to tune particular partials. This information is derived from actual measurements on bells. […]
