The Gradual is to be sung after the reading of the Epistle. It is ordinarily followed by the Alleluia or Tract, but in Masses that have more readings than normal, such as during Lent, these may be separated by another reading, or, if there are more than three readings, there is more than one Gradual, and finally the Tract, to separate each reading. In Eastertide, the Gradual is normally omitted, and a second Alleluia is sung in its place, except within the Octave of Easter. In what is now the ordinary form of the Roman Rite, the Responsorial Psalm normally takes the place of the Gradual, and is sung after the first reading, but it may be replaced by the Gradual.
