If I enjoy your music, I may keep you here to smooth away my cares; if your music offends me, I may send you to toil in the desert for your passage money. If I deem your playing just right for Farad’n, who is said to be an enemy of the Atreides, then I will send you to him with my blessing. Will you play on these terms, Tagir Mohandis?”
