(54)	Tubular bells with weights attached to nodes of fourth overtone for adjusting overtones to target frequency ratio

(57) Chimes or tubular bells generate sounds through vibrations of metallic tubes (2), and weight members (2c-2e) are attached to nodal points on each metallic tube where the nodes of the fourth overtone (f4) take place; the weight members (2c-2e) decease the frequencies of the third and fifth overtones (f3/f5) without an influence on the fourth overtone so as to regulate the first overtone, the fourth overtone and the third overtone to a target frequency ratio of 2 : 3 : 4.
