The MS corpus consists of Proper compositions arranged in complete masses (f. 1-155), Ordinary pieces (f. 155v-165), 90 sequences (f. 165-222), a few Gospel and Epistle Tro (f.222-231v), 33 cantiones (f. 232-246), 16 Benedicamus Tro (f. 247-251v), 19 Introit Tro (f. 251v-254v), 19 other Tro (f. 254v-261v) and 5 additions in later script. The script of both text and music is clear and precise throughout.
There are 4 polyphonic pieces, written in score, between ff.248v-256; they have barlines drawn thinly through both voices.
The three principal authors and donors of the MS were clerics who appear in the initial miniature, annotated 'scribebant'. Their names were Johannes de Perchausen, Otto de Wartenberch and Johannes de Geyrstal, and they belonged to the Augustinian foundation of Moosburg. The single copyist is named as "Ernestus scriptor de Landshuta".
