In the Christian East, there is a very long tradition of congregational singing, as I have noticed in my many visits to both Orthodox and Eastern Rite Catholic parishes. At no time of the Church year have I felt the floor shake as thunderously as does during the Paschal Season.

The reason for this is simple: it the Easter Chant “The Angel Cried,” which may be compared to the Latin  Hymn, “Regina Caeli, Jubila.”

Two beautiful renditions may be heard below.
