Royal Eijsbouts   Bell Foundry
                Asten, The Netherlands


Advanced computer program designs bell profiles and predicts partials.Swinging Bells

Chime Master's affiliation with the bell foundry of Royal Eijsbouts means we can supply you with a single bell, a peal of swinging bells, a chime, or a carillon with electrical and/or traditional mechanical clavier action.

Research and Campanology
Eijsbouts physicists and campanologists have developed, in cooperation with the University of Eindhoven, proprietery software that accurately predicts the vibrational characteristics of bells based on their profile (the combination of their inner and outer shape) and material composition. The calculations provide the frequency and amplitude of the dominant harmonic partials, as well as their decay characteristics.

The profiles and bronze alloy compositions of historic bells have been imported into this program for analysis. Improvements can be tested on the computer before test castings are made for verification purposes. These developments have lead to a number of standard bell profiles that provide a variety of timbral qualities.

The Hemony profile, named for the famous 16th century founders Francoise and Peter Hemony, provide a richly harmonic sound commonly heard in the Flemish region of Europe. Many listeners prefer the sound of the English profile modeled after the beautiful carillon bells cast by the 20th century founders Gillet and Johnston.

The Elusive Major Third
One of the musical challenges facing bellfounders since the Hemony's research into tuning, has been the third partial. No matter how the bell founders tried to vary the shape of their bells, the third remained minor. The natural vibrational characteristics of string and wind instruments is a major third partial. So, mainstream musicians historicaly have not accepted bells and carillons as serious musical instruments.
Computer modeling led to the development of the Major Third bell profile. Major third bells were used in the carillon at the Crystal Cathedral in Garden Grove, California.

Fine Tuning
Regardless of the technology used in the design of the bell, the musically trained human ear is the most valuable instrument utilized in the manufacture and tuning of the bells. Every Royal Eijsbouts bell we sell is a finely tuned musical instrument. So even if you purchase a single bell, you can be sure that bells added in the future will ring harmoniously together.

Chime Master/Eijsbouts Projects:
  • Co-Cathedral of the Sacred Heart, Houston, TX
      Campanile with 23-bell carillon with electric action, including a four-bell swinging peal. The Houston Chronicle has posted photos of the dedication, including the blessing of the bells (photos 85-87).
  • Historic Trinity Lutheran Church, Detroit, MI
  • Plainfield United Methodist Church, Plainfield, IL
      Addition of eight new bells to the original 1907 Meneely Watervliet ten-bell chime. New clappers and a new traditional carillon keyboard action that will support five more bells. Analysis of the original ten bells revealed a meantone temperament. The additional bells not only match the timbre of the original bells, but were also manufactured to retain the meantone tuning. Listen to a portion of the dedicatory concert by Tim Sleep.
