Small size neumes. The axis of the notation is slightly slanted to the right and the square puncta are not vertically piled one above the other. Custodes. Rare lozenges found as part of descending neume patterns. In the responsories ‘In omnibus’ Cantus ID 006920 and ‘Tribularer’ Cantus ID 007778 the lozenge is purposefully used to convey semitonal information. The lozenge is not used consistently in these two chants and it is found exclusively in descending neume patterns.
