| 20th century classical music - definition of 20th century classical music in Encyclopedia (2708 words) |
 | 20th century classical music was extremely diverse, ranging from the late Romantic style of Sergei Rachmaninoff to the complete serialism of Pierre Boulez, and from the simple triadic harmonies of minimalist composers such as Philip Glass to the musique concrète of Pierre Schaeffer and the microtonal music adopted by Harry Partch, Alois Haba and others. |
 | Neo-classicism, in music, means the movement in the 20th century to return to a revived "common practice" harmony, mixed with greater dissonance and rhythm, as the basic point of departure for music. |
 | One key difference between minimalism and previous music is the use of different cells being "out of phase" or determined by the performers, contrast this with the opening of "Das Rheingold" by Richard Wagner which, despite its use of triadic cells, has each part controlled by the same impulse and moving at the same speed. |
