Gradual

Between the Epistle and the Gospel, we have the Gradual. It consists of a Responsory and its Versicle. Formerly, the whole Responsory was repeated both before and after the Versicle, in the way now used with the Brief Responsories; only, the Responsory was exceedingly rich in notes. The Gradual is really the most musical piece in the whole Liturgy; and, as the rendering of it requires great skill, there were never more than two chanters permitted to sing it. When about to sing it, they went to the Ambo, which was a sort of marble pulpit, placed in the church; and it was on account of the steps, which led to the Arnbo, that this portion of the chant got the name of Gradual ; j ust as the Gradual Psalms were those which the Jews used to sing whilst ascending the steps of the Temple.
