A Gradual (or graduale) is a book which contains the chants sung during the Mass. It includes the music notation together with the words. Like the Breviary, it is divided into distinct parts according to the two main cycles of the liturgical year, which contain respectively all the parts of the liturgy which vary in accordance to a specific observance (proprium de tempore, 'proper of time' and proprium santorum, 'proper of saints') and those which are common to a specific category of saints, such as martyrs, confessors, virgins and so on (commune sanctorum, 'common of saints').

Each celebration includes different chants: the Introitus (the entrance chant, sung when the priest apporaches the altar); the Gradual Psalm (a responsorial chant which follows the reading of an epistle or other lection); the Alleluia; and the Sequence (sung before the reading of the Gospel; on certain occasions, such as during Lent, a Tract, a series of psalm verses, is sung instead of the Alleluia); the Offertory (sung during the offering of bread and wine at the Eucharist); the Communion (sung during the distribution of the Eucharist).

The manuscripts contains page-markers.

Proprium de tempore (Advent to Easter): starts on f. 1r. The 'proper of time' (or temporale) includes all the chants related to the moveable feasts of the year.

Litany: starts on f. 59v. It begins with the hypnotic invocation of a list of saints; each invocation is followed by the answer Ora pro nobis (with the plural variation Orate when more than one saint is invoked).

A series of other invocations, followed by the answer libera nos Domine ('free us, Lord') or te rogamus audi nos ('we pray you, listen to us'), comes after the list of saints. The singing of the Litany was part of the celebrations of the Easter Vigil.
