Protector noster aspice deus et respice

The incipit «Protector noster» is raised a fifthe higher, in a typical 5th mode intonation from Ffaut to Csolfaut, thus avoiding the plagal diathesaron found in other sourcer. This response reaches no more than a 2nd above the modal diapente, making it therefore indistinct mode of Ffaut. The following Verse however is perfect 5th mode. The word «tuos» notes the appearance of two plus (+) signs near Alamire.
