P-G (Guimarães) Arquivo Municipal Alfredo Pimenta N 656
Non-central bifolium. It contains chants for the feasts Purificatio Mariae, Vig. Joannis Bapt., Joannis Baptistae. It is worth noticing that the tractus 'Diffusa est' (Cantus ID g02214) and its verses (see fol. Arv) have been indexed in Cantus Index only in three sources, in all cases for the liturgical feast 'Purificatio Mariae'. The sources are F-Pn 776, P-BRs Ms. 34 and E-SAu Ms 2637 (see http://cantusindex.org/id/g02214). The following tractus 'Nunc dimittis' and its verses (fol. Av) seem to be also quite rare, being indexed in Cantus Index only in AUS-Sfl 376 and F-Pn 776, in both cases for 'Purificatio Mariae' (see http://cantusindex.org/id/g00076).
Several later-hand inscriptions on fols. Ar and Br.
Medium size neumes around a red line. The axis of the notation is vertical. Due to the poor material condition of the fragment, it is not possible to ascertain the original presence of custodes. The lozenge is not used consistently and, occasionally, the difference between a lozenge and a more or less square punctum is not clearly defined, see for example the neumes over ‘in letitia’ on fol. Av, 2nd text line. The lozenge is used either in isolation and as part of descending/ascending patterns of two or more notes on one syllable.
