Several of the sixteenth-century ornamentation manuals state that they are self-sufficient tutors; that instrumentalists and vocalists could learn the skill without further assistance from a teacher. While this may have been possible for one type of ornamentation, it did not hold true for the newer, dramatic, Neapolitan style of ornamentation that was heavily based on rhetorical models, and which needed careful guidance from an experienced teacher (Author).
