Wright, Craig, MUSI 112 Listening to Music, Fall 2008. Yale Open Course Ware: Music, Accessed 6/10/14, http://oyc.yale.edu/music/musi-112/lecture-10 License: Creative Commons Attribution-Noncommercial-Share Alike 3.0 Professor Wright delves into sonata-allegro form in some depth in this lecture. He focuses especially on characterizing four types of music found within a sonata: thematic, transitional, developmental, and cadential. He then moves on to discuss a different form, theme and variations, which is accomplished through the use of examples from Beethoven's and Mozart's compositions. Professor Wright and guest artist Kensho Watanabe then conclude the lecture by demonstrating a set of theme and variations through a live performance of Corelli's La Folia.
