Correction: a missing footnote

In my article “Difference, Disability, and Composition in the Late Middle Ages: Of Antonio ‘Zachara’ da Teramo and Francesco ‘Il Cieco’ da Firenze,” chapter 26 in the Oxford Handbook of Music & Disability Studies, edited by Blake Howe, Stephanie Jensen-Moulton, Neil Lerner, and Joseph Straus, pp. 517–28, there is a discussion of Petrus frater dictus Palma ociosa, and how his “deformed hand” (Palma ociosa) may have impacted his perception as a singer and a teacher in light of the importance of the (Guidonian) Hand in instructing singing. In the context of a paragraph of original research, cited articles, and common knowledge not requiring a footnote, this discussion is none of the above. I should have cited Christopher Page, The “Summa musice”: a Thirteenth-Century Manual for Singers (Cambridge: CUP, 1991), which, as Daniel Leech-Wilkinson’s Grove article notes, is the place where this theory is discussed (pp. 72, 158, and lines 692–96).>

I regret the omission and ask Page’s forgiveness for the oversight.
