Chanting the Benedicamus Domino during the week days in the Divine Office

Hi everyone,

I am singing the LOBVM and found out the following information regarding the Benedicamus Domino:

- The Liber gives variations for lauds, 1. and 2. vespers for: feasts (class 1, 2,3), feasts of the BVM, on Sundays during the year, during Advent/Lent and during Easter. (Liber Usualis p. 124-12).

- It also says how to sing the BD on Sundays for the little hours (e.g. Liber Usualis p. 273).

My question is as follows:

a) How am I supposed to chant the Benedicamos Domino for matins, lauds and vespers on a week day without any feasts or Sundays?

b) How am I supposed to chant the Benedicamos Domino for the little hours on a week day without any feasts or Sundays?


Thank you for your help and inputs
