This document outlines activities for teaching students about 20th century musical styles. It includes having students listen to compositions by Debussy, Schoenberg, Bartok, Stravinsky, and Ravel to observe melodic progression, rhythm, texture, and mood. Students then analyze and discuss the music, identifying which pieces they enjoyed most and the distinct musical styles of different composers. Additional activities include creating video films portraying 20th century elements, performing songs from West Side Story, and conceptualizing a localized presentation of West Side Story or Porgy and Bess.
