This week Dr. Tobin discusses Claude Debussy’s Book I Prelude Engulfed or “Sunken Cathedral”. It is based on the legend of the sunken town of Y off the Breton French Coast. Dr. Tobin discusses how Debussy paints the image of a sunken cathedral that rises from the depths of the sea. After the discussion, he includes are recording he made on the piano Debussy composed it on, the Bluethner in Brive la-Gaillarde, France. For further contrast, Dr. Tobin includes a video he made at Mont St Michel on the coast of Normandie and a recording made on a Steinway Model A piano in Wetizkon, Switzerland.
