Yale Open Course Ware: Music, Accessed 5/10/14, http://oyc.yale.edu/music/musi-112/lecture-7 License: Creative Commons Attribution-Noncommercial-Share Alike 3.0 Professor Wright explains the way harmony works in Western music. Throughout the lecture, he discusses the ways in which triads are formed out of scales, the ways that some of the most common harmonic progressions work, and the nature of modulation. Professor Wright focuses particularly on the listening skills involved in hearing whether harmonies are changing at regular or irregular rates in a given musical phrase. His musical examples in this lecture are wide-ranging, including such diverse styles as grand opera, bluegrass, and 1960s American popular music.
