In this chapter we examined the Impressionist style of music and its two main composers, Ravel and Debussy. We also looked at a new approach to harmony and composition developed by Schoenberg, Berg, and others that became known as Expressionism. We then briefly touched on the style called primitivism and the music of Igor Stravinsky and examined the Neoclassicism of Stravinsky and others. We saw how the minimalist composers sought to create music from its most fundamental rhythmic and melodic elements, returning to the consonant sounds of triads and the strict application of steady meter. We then discovered the unique- ly American, yet contrasting styles of Aaron Copland and George Gershwin—Copland creating an American symphonic style and Gershwin creating a style which incorporated jazz music. We learned that musique concrète was a combination of recorded and electronic sounds and that the German composer Karlheinz Stockhausen was the leader in elektronische Musik. We saw that the Princeton University Laptop Orchestra is an important leader in laptop computer ensembles. Finally, we looked at music for motion pictures and at one of the most recent developments in electronic and digital entertainment: music for video games.
