Later-hand inscriptions on fol. Bv (written reversed with respect to the text) and one on fol. Br ('A-10-1-43').
Large size neumes. The axis of the notation is vertical. The lozenge is used both isolated and as part of ascending and descending compound neumes, such as pes, torculus, and clivis. The lozenge, however, is not used consistently. For instance, in the second chant on fol. Ar there are no lozenges but only square puncta. In some cases, even if the lozenge is used in the piece, there is some confusion with its spatial placement; see for example the responsory "Laetabitur iustus" (Cantus ID number 007064) and its consecutive responsory verse “Letamini in domino” (Cantus ID 007064a) on fol. Av. Here, in both chants the lozenge was occasionally written on consecutive steps, see for example “sperabit in” in the responsory or the beginning of the verse “Letamini in domino” below, on the same page. Moreover, while it seems possible to identify the mode of the responsory as the 7th (with the red line meaning B and the finalis on G), there are more doubts on the identification of the mode in the verse if we take into account only the notation.
The difference between a lozenge and a more or less square punctum is generally clearly defined. However, occasionally there is some confusion with the virga and the lozenge because 1) the virga is made of a lozenge with a descending stem placed on the left and 2) for the poor condition of the fragment. Similar situation occurs with the oriscus, which is made of a lozenge followed by a smaller lozenge with a descending stem on the right, see for example on fol. Br (right half) the first music line with the beginning of the antiphon “E(…) sancta dixit” (Cantus ID 003024) or the oriscus on “Lignum”, on the third music line below.
