Step-by-step explanation:
In the 20th century, there were four main paths for new conceptions of tonality. These paths included:
- Atonality: Composers like Arnold Schoenberg experimented with atonality, which is music without a central, binding key, and included unexpected notes and dissonance in their works.
- Twelve-tone music: Schoenberg also invented a twelve-tone scale, which became an important influence on avant-garde musicians and composers.
- Impressionism: Some composers, like Claude Debussy, explored impressionistic music, which focused on creating an atmosphere or mood through unique harmonies and colors.
- Experimentalism: Other composers, such as John Cage, embraced experimentalism, using unconventional techniques and elements like chance and silence in their compositions.
