In the Tridentine Mass, the celebrant himself reads the Gradual with the Alleluia, Tract, or Sequence immediately after he has read the Epistle, and at the same place, even if the choir sings it too. There is no rule for the distribution of its parts within the choir. All may be sung straight through by the whole choir, but it is more common to divide the texts so that some parts are sung by one or two cantors. A common arrangement is that the cantors sing the first words of the Gradual (to the asterisk in the choir-books), the choir continues, and the cantors sing the verse. Normally it is all sung to plainsong.
