Repetition and variation are important components of the music of Morton Feldman—components that he extracted from his observation of Persian carpet designs.
Rug design and music are arts that use symbolic language to express certain concepts with a focus on the idea of unity in multiplicity. The designs of some Persian carpets are based on the weaver’s mind map, which resembles Feldman’s musical approach. Key elements of these carpet patterns correspond directly to Feldman’s use of repetition and symmetry in his works.
This according to “A study on the rug patterns and Morton Feldman’s approach” by A.A. Javadi and M. Fujieda (International journal of music science, technology and art II/1  48–53; RILM Abstracts of Music Literature 2020-3041). Many thanks to Improbable research for bringing this study to our attention!
