In this article, composer and educator Mike Heffley analyzes the libretto and score of a Braxton's magnum opus, the opera Trillium R (Shala Fears for the Poor) of 1991. With the term "speculative music," Heffley designates music as a "speculum," or a mirror of the natural world or cosmic order. Heffley considers the opera's libretto in the context of the entire corpus of Braxton's writings, particularly his Tri-Axium Writings of 1985. Heffley argues that Braxton's use of language is "a driving force behind, first, his music, and, further, his body of work as a whole . . ."
