Schoenberg used atonality in the music of his middle period.

桑伯格在中期用无调性方式作曲。

This paper focus on the two systemized and influential atonality theories, the symmetry theory and the picth class set theory.

本文以后调性时期中较为成熟并有较大影响的两种理论体系——对称理论与音级集合理论作为研究对象。

His basic musical idioms were based on the tradition of tonality, but he also, if necessary, resorted to dissonances and occasional atonality.

他的音乐语言根基是传统的、有调性的，但为了表现的需要也使用不协和音响与偶然的无调性。

Idea and imagination are reciprocal causation. On the on hand, an abstract music image is created by the atonality and complex playing skills.

乐-曲所表达的意与象二者互为因果，一方面利用无调性以及混合的演奏技法表达充满想像的、-抽象的音乐形象。

Arnold Schoenberg's early works of atonality, because of the structural functioning of missing of "tonality", can only keep unity by dint of "strengthened theme coherence".

勋伯格初期无调性音乐创作，由于已失去“调性”这一深层结构力作用，因此只能借助“强化的主题一致性”来保证作品的有机统一性。
