Timothy Johnson contends that Nixon in China goes beyond minimalism in important ways. Adams had been inspired, in developing his art, by minimalist composers such as Philip Glass, Steve Reich, and Terry Riley, and this is reflected in the work by repetitive rhythmic patterns. However, the opera's complex harmonic structures are very different from the simpler ones in, for example, Glass's Einstein on the Beach, which Adams terms "mindlessly repetitive"; Johnson nevertheless considers the Glass opera an influence on Nixon in China. As Glass's techniques did not allow Adams to accomplish what he wanted, he employed a system of constantly shifting metric organizational schemes to supplement the repeated rhythms in the opera. The music is marked by metrical dissonance, which occurs both for musical reasons and in response to the text of the opera.
