Wind chimes are chimes
constructed from suspended
tubes, rods or other objects
and are often made of metal
or wood. Sound can be
produced when the tubes or
rods come in contact with a
suspended central clapper, in
the form of a ball or horizontal
disk, or each other. Modern
wind chimes have their origins
in Indian wind bells. By the
second century CE, these wind
bells were being suspended on
the corners of large pagodas
with the purpose of scaring
away birds and evil spirits,
they are also thought to be
good luck in parts of Asia and
are used in Feng Shui. Wind
chimes produce pleasant
ringing sounds and are hung
by the windows during hot
humid summers in order to
bring cooling relief.
