P-G (Guimarães) Arquivo Municipal Alfredo Pimenta N 161
The liturgical feast remains unidentified even though some of the chants suggest an attribution to 'Inventio Crucis' or 'Exaltatio Crucis'. Unfortunately the chants on this fragment are not found in the same order in any of the manuscripts currently indexed in the Cantus Index net of databases. Further details on the unidentified chants in this fragment can be found in the musical index (right-hand side of this page).
Big size neumes. The difference between a lozenge and a more or less square punctum is always clearly defined. The axis of the notation is vertical. The lozenge is randomly used at different heights always as part of compound neumes in a descending melodic movement. The lozenge is not used in isolation.
This fragment belongs to a group of fragments currently held in P-BRs and P-G which share the same style of notation: P-BRs Fragments 1, 3, 10 (fragments 1 and 3 originally belonged to the same codex); P-G C 1372, C 1429, N 133 (fragments C 1372 and N 133 originally belonged to the same codex), N 161, and P 217. From a notational standpoint, the main difference between these sources is the shape of the custos, however, P-G C 1429 and P 217 are too mutilated and today we don't know if custodes were originally written on these sources or not.
