The first part of the Bamberg Codex contains 100 double motets, which are three-voice pieces with two contrapuntal lines above a cantus firmus. Forty-four of the motets have Latin texts, 47 have French texts, and 9 are macaronic. This is followed by a conductus and 7 settings of hockets. The musical notation is similar to that used in the Montpellier Codex, although some advances in notational clarity are evident. These motets were likely composed between 1260 and 1290, and are generally in the style associated with Franco of Cologne.
The second part of the Codex contains two theoretical treatises, one by Amerus and one anonymous, as well as two motets added later.
