In other churches and rites, there are fragments of the psalms once sung between the lessons that correspond to the Roman Gradual. Their placement and structure depend strongly on how many readings there are. In the Byzantine Rite the reader of the epistle first chants "the Psalm of David" and then the "Prokeimenon of the Apostle", both short fragments of psalms. The Armenian Rite, which has kept the older arrangement of three lessons, includes between each a fragment called the "Saghmos Jashu" (Psalm of dinnertime) and the "Mesedi" (mesodion), again a verse or two from a psalm. The Nestorians use three verses of psalms each followed by three Alleluias (this group is called "Zumara") after the Epistle. The present Ambrosian Rite sometimes has a Prophecy before the Epistle, in which case there follows the "Psalmellus", two or three verses from a psalm, which corresponds to the Gradual. The Mozarabic Rite has three lessons, with a psalm ("Psallendo") sung between the first two. Among Protestant churches, Lutherans sing a Gradual either between the Old Testament and the Epistle or the Epistle and the Gospel readings during the Divine Service.
