This database, created by Dr Tosca A.C. Lynch (https://oxford.academia.edu/ToscaLynch), includes all the notes attested in the ancient Greek musical documents collected in the standard edition DAGM (Pöhlmann, E. and West, M.L., 2001, Documents of Ancient Greek Music, Oxford: OUP). Dr Lynch will present historically informed interpretations of these data in a series of articles devoted, respectively, to: –the Classical/Hellenistic harmonic system and the relative documents (marked as BC in this database); –the Imperial harmonic system and the relative documents (marked as AD in this database)Dubious readings follow Pöhlmann and West; DAGM 17-18 are grouped with Imperial documents, as discussed in the articles.
