This week Dr. Tobin is taking a suggestion from Jason Hoogerhyde, Professor of Composition at Southwestern University, to discuss the Book II Prelude Broulliards.
Dr. Tobin did a thesis which explored abstract pitch relationships in Debussy Preludes. This week the material is rather abstract, but he tries to keep it understandable. Debussy uses abstraction to create the image of mists and fog, to have blending and overlapping contrasted with flashes of light and clear white and black key contrasts.
