Three Wind Chimes

The birds chirp from the trees around the porch as an easy breeze blows agains the wind chimes. They seem to create a melody together. The birds sing to the music of the wind. 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 with each other. Wind chimes may be used to observe changes in wind direction, depending on where they are hung, when they commence to sound.
