The lake in Richmond Park had frozen over for the first time this winter. People were breaking off pieces of ice from the shore line or picking up stones from the paths, and skimming them over the frozen surface of the water.
To my amazement, each stone played the same musical note as it bounced, the note D. ‘Chook-chooka-chooka-chooka-chooka-chhhhhh’, sang the stones on D as they skittered to a stop far out on the ice. All around the lake, in the brilliant winter sunshine, the ice rang out like tuned percussion. I had not thought of the lake as having ‘a note’ before.
