8-year-old Kaley Christley, left, and her little sister Paige (right), 8, watch in amazement as their brother, 9-year-old Christopher sends West Virginia-made marbles down musical wooden marble tree during a Music in the Mountians workshop August 23 at the Raleigh County Public Library as part of Beckley's Appalachian Festival. The glass marbles came from The Marble King based in Paden City, and created a range of musical sounds as they worked their way down the tree. Pouring several marbles at once made the sound of water flowing in a stream.
