Emi Chusuk is a great musical composer from the Legends of Dune Series by Brian Herbert & Kevin Anderson. Emi Chusuk is a prominent musician from the Old Empire before the Time of Titans came to be. His music is complimented beside those of Brahms and Mozart. In the 1st book, The Butlerian Jihad, Erasmus, a thinking robot, attempts to woo Serena Butler, the daughter of the Viceroy, by playing what he calls great music on a piano in front of his slaves and Serena Butler. The music Erasmus composes sounds amazing like those of Chusuk and Brahms, but conveys no feelings to the audience.
