Answer:Impressionism and Expressionism in music are two different styles that emerged in the 20th century. Impressionism in music focuses on creating a mood, feeling, or atmosphere rather than telling a clear story. It often uses gentle rhythms, soft dynamics, and unusual scales like the whole-tone scale. The melodies are flowing, and the harmonies are light and blurry, like a painting made of sound. Claude Debussy is a well-known composer of impressionistic music, with famous works like Clair de Lune and Prelude to the Afternoon of a Faun. Another impressionist composer is Maurice Ravel, known for Boléro and Jeux d’eau.On the other hand, Expressionism in music is about showing intense emotions such as fear, anger, and sadness. This style often uses atonality, meaning it does not follow a key or traditional harmony, and the sounds can be harsh or disturbing. The melodies are sometimes sharp, with sudden changes in dynamics and tempo. Famous expressionist composers include Arnold Schoenberg, who composed Pierrot Lunaire and Verklärte Nacht, Alban Berg with his opera Wozzeck, and Anton Webern, known for Five Pieces for Orchestra. While Impressionism creates peaceful and dreamy music, Expressionism expresses raw, deep, and emotional experiences through sound.Let me know if you need more help!
