Why does the jingle of a furin give us a settled, relaxed feeling?
The vibrating body of a furin emits sounds of different
frequencies, because of its complicated shapes. If they are
overlapped, they produce fluctuations. Also the tanzaku
flaps erratically in the wind. Being stimulated by these
overlapping and erratic sounds along with fluctuations, people
feel comfortable with the sound of the furin, since our bodies
have the rhythm of such fluctuations, which relates to the
rhythm of life in nature
