Church bells

Inspired by the old masters, a deep inner „longing for the Stradavarius amongst the bells“ came to life for the brothers Peter and Johannes Grassmayr.

The findings from the application of modern tools (i.e. computer simulations) merge with the knowledge from old traditions and handcraft documents pertaining to this magnificent bell quality. The secret of the Grassmayr bells lies in their special waist (bell shape), their manufacturing process and their partial tones, which have been aligned to each other in sonorous harmonie.

As a consequence, the bells from the Grassmayer foundry fit perfectly with the „sound“ of SchlagZu.

The Bell as a Musical Instrument

In order that even the smallest bell is evenly matched tonally with deeper bells, the SchlagZu bells have a weight progression. This means: the smaller the bell, the thicker the bell wall in proportion.

The specification for a bell is always made according to the single most intensively perceptible main tone, the so-called strike tone or nominal. For a bell as a musical instrument, it is decisive,

  • that the strike tone (nominal) as the strongest perceptible sound conveys a special sensation for the hearer at the bell's toll.
  • that the partial tones prime, super octave, lower octave, double octave, triple octave be individually formed and ring pure after the cast due to exact calculation – tuned exactly to a cent.
  • that the bell echo (length of reverberation) is long. According to the „Limburger Guidelines“ (quality standards for bells), the lower octave must reverberate for one second per centimeter of bell diameter after three strong strokes.

The SchlagZu Bells from the Grassmayr Foundry significantly surpass this requirement.

The Bell Stand

The bell stand has been newly developed especially for use in the orchestra. It is made of separate laser-manufactured parts and is equipped with an easy to handle height adjustment feature which offers safe transport in the lowest position and a comfortable playing situation in a higher position. Existing bells can be upgraded with our bell stands. The floor plate can be ordered optionally with or without individual engraving.


Bell Surface

Although sound development is the most significant criteria for bells as „music instruments“, the cast surface bespeaks the quality of workmanship. „As inside – so outside“.
The particular composition of the special clay for the bell mold enables the bell to avoid having to be greatly reworked, for example because of many parting lines, a rough outer surface or „cellulite“.


Bell Decoration

From a technical point of view, bells don’t need crowns or ornamentation to produce their sound. However, bells do obtain a symbolic and, because of their usual long lifespan, a historical importance through their ornamentation.
There are no ‘guidelines’ for ornaments. To a greater degree, they open the possibility for the customer to give his bell its unique distinctive feature and significance.
