To-day we offer our readers this booklet containing the music for the Mandatum as it was celebrated before Pius XII’s reforms of Holy Week, according to the musical norms followed by the Antiphonale monasticum. The latter, published in 1934, reflected the advances that Gregorian chant scholarship had made since the publication of the Graduale romanum in 1908 and the Antiphonale romanum in 1912 (this explains the differing melodies of the same antiphons in the Roman and monastic uses).
Unhappily, a full official version of the Graduale reflecting these developments has never been produced, even after the promulgation of Sacrosanctum Concilium, which in article 117 states that “the typical edition of the books of Gregorian chant is to be completed; and a more critical edition is to be prepared of those books already published since the restoration by St. Pius X” . Two privately-produced editions—the Liber gradualis and the Graduale novum—are in the course of being published, although it is regrettable that they are designed for use in the Novus Ordo Missae rather than the traditional Mass (even if it is easy enough to adapt them).
 Compleatur editio typica librorum cantus gregoriani; immo paretur editio magis critica librorum iam editorum post instaurationem sancti Pii X.
