The Lecture Recital was given on July 28, 1981. Its subject, Carl Reinecke's "Undine" Sonata, is a major work written for flute during the nineteenth century. Reinecke was highly respected as a conductor and pianist; his great love for the classical style tempered his Romanticism and conditioned his approach to both performance and composition. The subtitle of the sonata suggests a program based on Friedrich de la Motte Fouqué's short novel, Undine. Although few flutists are familiar enough with this tale to recognize its application to the sonata, an exploration of the program implied by the subtitle adds materially to an understanding and appreciation of the work; to a large extent, the content of each movement is conceived in terms of the program. Further examination of Reinecke's life and philosophy reveals that both the choice of this particular literary subject and the uniting of Romantic pictorialism with classical form were entirely characteristic of his writing. Since Reinecke specified no program other than the subtitle, any relating of the music to specific events in the story is necessarily a subjective postulation. The musical content of the work makes it fairly easy to establish a broad correspondence between the movements of the sonata and the progress of the story, however, leaving details to the individual imagination. Within the paper, the pictorial aspects of the music are explored in the belief that they can not only assist in an appreciation of the work, but also provide a guide to the performer for its interpretation.
