The Office
There are four office cycles:
-the Canonical Office is the principal office, it is sung, in the chancel, daily
-the Sung Office of the Virgin is sung in the chapel of the Virgin, daily
-the Said Office of the Virgin, is sung recto tono, partly in the chancel, partly out of the chancel, daily
-the Office of the Dead is sung or said (recto tono) on some days

-the offices found in the Sarum Books of Hours or Primers are intended for lay-folk. The Office of the Virgin contained in these books is similar, but not the same as the Said Office of the Virgin listed above.
