Improvisation and Extemporaneous Change in the Book of Mormon (Part 1)

Joseph Smith made various refining changes to the Book of Mormon text, most of them minor and grammatical in nature. However, one type of textual change has been virtually unstudied in Book of Mormon scholarship: extemporaneous change that was present the moment Smith dictated the original text to his scribes. This type of change appears to have been improvisational, a fix or repair made in the middle of a thought or expression. I study these improvisations in depth — where they might appear historically, their purpose, and their authorship — in two articles. The evidence points to ancient authors and editor-engravers whose extemporaneous changes appeared during the early layers of the Book of Mormon’s construction. In this paper, Article One, we study the improvisations found in the quoted ancient texts of ancient prophets, then in the embedded texts of authors who improvise, and finally in the improvisational narratives of the major editor-engravers — Mormon, Nephi, and Moroni.
