The tone and the day's psalms

This week's tone is 7Eight tones — the Octoechos

What is a tone?

A tone is not a psalm number. It is the mode in which that week's resurrection hymns are sung — the whole week's Vespers, Matins and Liturgy are set in one tone.

The Psalter is divided into twenty kathismata and, by the usual rule, is read through once a week. Appointed for this day:

This is the usual rule. In Great Lent the Psalter is read twice a week, and the kathismata are divided differently.
