“ When such masses are performed, whether in a concert-room or church, it is indisputable that the motet ought always to be included. Sometimes one composer founded a mass on another composer’s motet; thus Soriano’s fine Missa, Nos autem gloriari, is based upon a motet by Palestrina. When a motet was in two movements the second movement almost always ended with the last clauses of the first, both in text and in music, thereby sometimes producing a distinctly modern impression of da capo form. ”
