Restitution and rsigns from H with melody from Sandhofe (KA 58v) modified (first part) with respect to the typical 7th mode invit.

Episema+space to indicate neumatic rupture in -ri- (maria)

Undoing this: this is not a strong neumatic rupture but a very standard way to notate this. Having a space in the square notes is sufficient.

Added NABC and modified TEcum in light of the German mss which have sol-la-do-si-la-do / la-sol, in which the quilisma on si has been omitted and the last not has been attracted from si to do, resulting in sol-la-si-do-si-la-si / la-sol.
