In the Byzantine rite, a set of three or four short antiphons to the gradual psalms (verses from Psalms cxix–cxxx and cxxxii) sung at Sunday Orthros . There is a set for each of the eight modes. Although they were compiled in the 8th century, probably by Theodore of Stoudios (c794–7), the oldest surviving melodies are contained in manuscripts from the 10th and 11th centuries and are written in Chartres notation (GR-ATSgreat lavra γ 67; ATSvatopedi 1488; see Byzantine chant, §3, (i), (b) ). These settings provide unique evidence for ancient psalmodic practice and the use of cadence formulae in the Byzantine psalm tones.L.
