At the initiative of SchlagZu, this wonderful synthesis of direct bell sound, reduced weight and the potential depiction of lower registers than would be possible, for example, with church or tubular bells, emerged from the Grassmayr bell foundry. Thesecret lies in their form: like church bells, the cup bells for orchestras ring with numerous varying partials following a single strike. However, the fundamental tone immediately emerges, so that the striking tone matches the nominal tone.
Due to their compact design, cup bells for orchestras are flexible to use and offer entirely new playing options; i.e. one above the other for Hindemith's „Metamorphosis“.
