The Paschal troparion or Christos anesti (Greek: Χριστὸς ἀνέστη) is the characteristic hymn for the celebration of Pascha (Easter) in the Eastern Orthodox Church and those Eastern Catholic Churches which follow the Byzantine Rite. Like most troparia it is a brief stanza often used as a refrain between the verses of a Psalm, but is also used on its own. Its authorship is unknown. It is nominally sung in Tone Five, but often is sung in special melodies not connected with the Octoechos. It is often chanted thrice (three times in succession).
