On The Timbre-Texture Structure Of Gy(?)rgy Ligeti's "Atmosphères"

Gy(o|¨)rgy Ligeti(1923—2006) is one of the most influential composers in the 20the century.His invention and practice of micropolyphony technique play a decisive role for the initial success of his works in the western music world.His unique thinking and individual muisc style have a far-reaching effect on musicians after 1960s and the creation and development of many other music schools.Gy(o|¨)rgy Ligeti is not a productive musician,but he never stops his exploration of music in which he creates unique "Ligetic Style",putting his works on the top of 20th century music.As one of the most representative works of the author in 1960s,"Atmospheres" employs timbre-texture structure which plays a crucial role in the construction of the work.For this reason,this paper gives a detailed analysis of timbre-texture structure from the aspect of orchestration.The paper is composed of three parts.Part one is a brief introduction of the composer and of different stages of his composition.The social background of the work and the features of structural thinking are discussed in this section.Part two and part three are the main section of the paper which uses examples to explicate the features,processing mode,and the principles of timbre-texture structure.From the aspect of orchestration,this paper gives a systematic research of "Atmospheres".Our discussion focuses on the orchestral formulation of the work,the acoustics resources employed,horizontal development and arrangelnent of the timbre-texture structure,and the integrated features of the structure.At the end of the paper,we give a summary of the timbre-texture structure employed in Gy(o|¨)rgy Ligeti's "Atmospheres".
