Abstract
A tuned musical handbell has been devised which has a surprisingly excellent musical tone quality. A bell casting made from aluminum is sized and tuned by metalworking processes to frequencies below 196 Hertz. Aluminum alloys, such as numbers 319, 356, and Precedent 71 are suitable. The aluminum handbells are produced as individual elements of a complete set which include the use of aluminum for frequencies below 196 Hertz, and bronze for frequencies above 196 Hertz.
