A popular Easter hymn, O filii et filiae is.

Originally, only nine verses, written by the Franciscan friar Jean Tisserand, made up the hymn. Discipulis adstantibus, Postquam audivit Didymus, and Beati qui non viderunt were later added. A triple Alleluia is sung as the refrain between each verse.
Scheduling what verses to sing according to the Gospel read within the days of the Easter octave would be one way of aligning our meditations with a particular moment that occurred after the Resurrection of the Lord. Below then can be our guide:
