The program of chants is drawn primarily from the 'Proper' of the Palm Sunday liturgy (notably the Tractus Deus, Deus meus), from the Missa in Coena Domini (the Antiphons Nos autem gloriari oportet, Ubi Caritas, Dominus Jesus, and Maneant in vobis), and from pieces (mostly Responsories) taken from the Nocturns of the Easter Holy Triduum (Omnes amici mei, Caligaverunt oculi mei, In monte Oliveti, Judas mercator pessime, etc.).
