No, the sound depends on the thickness of the metal part and the size of the cowbells. In fact, both factors influence the sound, which will be higher or lower also depending on the topographical characteristics of the territory. In Valais, where there are many steep mountains, the sound will have to be higher and more penetrating than for example in the Vaud Jura, which is a flat territory and where the cowbells have a warmer and rounder sound.
