GRASSMAYR Organ cups

Organ cup bells are singing bowls raised to a zenith of musical perfection.


Based on computer simulations, the forms are precisely calculated in such a way that the organ cups can be used as musical instruments, e.g. in organs.


Each organ cup is cast so as to correspond to the desired major note. Further, ultimate fine tuning can be requested by the customer with specifications such as a1 = 440 Hz or a1 = 444 Hz, etc. Each individual organ cup is tuned to a precision of the major tone to exactly +/- 3 Cent  (the gap between two half tones is 100 Cent).
