Final answer:
Arnold Schoenberg was associated with expressionism, an artistic movement emphasizing inner feelings and emotional experiences, rather than impressionism.
Step-by-step explanation:
The Austrian composer Arnold Schoenberg worked with expressionism, not impressionism. Schoenberg's approach to composition was innovative for his time, focusing on atonality and the twelve-tone technique, which defied the traditional tonal system of Western music. This method of composing was part of the larger expressionist movement, which sought to express inner feelings and emotional experiences rather than physical reality. In contrast to impressionism, which was more concerned with depicting the impression of a moment, especially in terms of the effects of light and color, expressionism was characterized by its focus on the expression of emotional experience and often featured dissonance and unexpected notes to evoke a sense of unease or intensity.
