DMA First Exаm–Fаll 2024 Scоre Essаy Questiоns   DIRECTIONS: Answer the questiоns about TWO of the three pieces below. Follow the directions listed here exactly. Failure to do so will result in not passing the exam. If you consulted sources in your research, please cite them in general by using author and/or title names. All essays should be at least 750 words long in total.   SCORE ESSAY PIECE 1 (1.5 hours)  John CAGE, Sonatas and Interludes for Prepared Piano (Sonatas 1 and 5, and Interlude 1)   John Cage is known for his innovative approach to discovering new sounds, especially in his prepared piano works like Sonatas and Interludes for Prepared Piano. In these pieces, Cage moved away from traditional harmonic and tonal relationships. Please answer the following two parts in prose and clearly mark each part (i.e., Part I). Part I. Musical Organization, Expression, and Aesthetics How did Cage organize his music in works like the Sonatas and Interludes after removing conventional harmony and tonality? What principles or techniques did he use to structure his compositions instead? Consider the score from the perspective of expression. What was Cage attempting to express in these works? How do the sounds he used connect to his expressive goals? Part II. Analytical Comparison Compare and contrast the First Interlude with either Sonata No. 1 or Sonata No. 5. In your analysis, briefly focus on the following elements: Rhythm Form Melody Harmony Timbre   SCORE ESSAY PIECE 2 (1.5 hours) Guillaume DU FAY, Agnus Dei from Missa l'homme armé In terms appropriate to the period, analyze the structure of this movement. Explain how Du Fay uses phrasing, texture, and melody to signify divisions of the text and the movement’s function within the Mass. Then, contextualize Du Fay’s use of L’homme armé within the larger Renaissance tradition of using pre-existing musical material for organizational, aesthetic, and intertextual purposes. Why did composers so frequently turn to existing sources like the L’homme armé tune to create their own works? How did this practice differ between composers and generations, such as between Machaut and Du Fay or between Du Fay and Josquin, for example?   SCORE ESSAY PIECE 3 (1.5 hours) Felix MENDELSSOHN, Songs without Words, op. 19, no. 1 Part I. Explore how Mendelssohn’s piece reflects aspects of 19th-century artistic and economic life. You might begin by discussing several key musical features of German Romanticism. Then, consider who the intended performers and audience might have been, and why they were significant within the context of that time. Part II. Next, analyze the formal structure of the piece, either through a detailed diagram or written description. Consider both the overall form and the smaller phrase structures within the piece. Pay special attention to key areas and thematic ideas. You might start by identifying cadences, using these formal divisions to guide your analysis.
