The Roman Gradual (Latin: Graduale Romanum) is an official liturgical book of the Roman Rite of the Roman Catholic Church containing chants, including the proper and many more, for use in Mass.
The editio typica dates from 1908.[1] The latest edition of 1974 takes account of the 1970 revision of the Roman Missal.
In 1979, the Graduale Triplex: The Roman Gradual With the Addition of Neums from Ancient Manuscripts (ISBN 978-2852740440 in English (1985), ISBN 978-2-85274-094-5 in Latin) was published. It added reproductions of the neumes from ancient manuscripts placed above and below the later notation.
