The Creature of Stone is a devotional form of music directed toward the worship of Aye the Furs of Heather originally devised by the elf Lora Shorebirth. The form guides musicians during improvised performances. A singer recites any composition of The Wooden Field. The entire performance should bring a sense of motion and is very slow, and it is to start loud then be immediately soft. The melody has long phrases throughout the form. Only one pitch is ever played at a time. It is performed without preference for a scale and in free rhythm. Throughout, when possible, performers are to play rapid runs and modulate frequently.
