P-G (Guimarães) Arquivo Municipal Alfredo Pimenta N 022
There are only three notated antiphons on this fragment. The third one (Dixit dominus) has Cantus ID a00026 and it is rarely found. Up to the present date, it has been recorded only in two more sources: P-BRs Ms. 32 fol. 126r for the Magnificat of Dom. Sexagesimae; and at the beginning of the single-page fragment E-TUY Fragmento 18 for the Magnificat of Dom. Quinquagesimae.
Later hand inscriptions on the verso.
Medium size neumes around a red line. Custodes. The axis of the notation is vertical. The difference between a lozenge and a more or less square punctum is clearly defined. The lozenge is used consistently either in isolation or as part of a compound neume (descending / ascending pattern).
