Answer 1

Arnold Schoenberg is best known for pioneering the technique of twelve-tone serialism, also known as dodecaphony. This method involves using a series of all twelve notes of the chromatic scale to create a composition, ensuring that each note has equal importance and avoiding traditional tonal hierarchies. Schoenberg developed this technique as a way to move beyond the constraints of tonality, which dominated Western music for centuries. His work laid the foundation for much of modern and contemporary music.
