The codex begins with a trope written in Greek on the first page and a Latin versus on page 3. It is followed by one of the most extensive known collections of such tropes in the East Frankish kingdom, which were mainly used to extend the previously existing liturgic repertoires. It begins on the fourth page with the words “Incipiunt tropi carminum in diversis festivitatibus missarum canendi” (Here begin the tropes that are to be sung along the mass chants of various celebrations). Many of the collected tropes are chants which were used as additions to existing ones, provided musical renditions of their texts, or which simply extended older liturgic chants. The tropes are accompanied by a musical notation in the form of neumes, an at the time novel way of melodic transcription.
