Katabasia or Katavasia (Greek καταβασία, from καταβαίον, "descend") is a type of hymn, and the last troparion of an ode of a canon, chanted in the Eastern Orthodox Church and those Eastern Catholic Churches which follow the Byzantine Rite. Its name is derived from the Greek word katabasia for descent, so called because the cantors used to descend from their stalls and unite in the middle of the church to sing them.[1]
The katabasia is an irmos that is sung at the end of an ode of the canon. The katabasia is chanted by the choir, who descend from their seats (kathismata) and stand on the floor of the church to sing it, whence its name. Katabasia are chanted at Matins and sometimes during other Divine Services such as Compline. They are also found at other occasional services such as the Mystery of Unction or funerals.
At Matins, on ordinary weekdays, only Odes 3, 6, 8 and 9 have katabasia. On Sundays and higher-ranking feast days, there will be a katabasia at the end of each ode (these are called Festal Katabasia). Most of the other services which use katabasia will have them only after the 3rd, 6th, 8th and 9th odes.
