De l'« êta négligé » au « pi tiré vers le bas » : problèmes d'identification et de dénomination des signes musicaux d'après le P. Mich. inv. 1205.

P.Mich. inv. 1205 is a small papyrus fragment containing the remains of an instrumental music score. Relying on a paleographic and musical analysis to reinterpret the reading of the most frequent sign, the article substantially modifies the melodic structure, and raises the question of the link between the establishment of intrumental semiography and its nomenclature, leading to a better understanding of tables of musical signs in the treatises copied during the medieval period.
