At seminary, the pre-Vat-II tradition was followed, Alma Redemptoris Mater from Advent to 2 Feb and then Ave Regina Caeolorum onwards and through Lent (and almost always in Latin).
My own personal practice is to try to harmonise with the post-Vat-II seasons, so having used the Alma throughout Advent, I switch to Ave Regina Caeolorum - and I often make use of the English translations in the Breviary.
#117, the English Alma, fits the tune of "Tell out my soul"... at least until the last line which is 2 syllables longer than one would expect.
#119, the English Ave Regina Caeolorum fits to Jerusalem!
This does mean I have to resist the temptation to use #125 in Christmastide, an English setting of the Salve Regina which can be sung to Good King Wenceslaus!
Come Lent, I will be back to O Sanctissima #126 or its English equivalent #127. But (not being gifted at sight-reading, so practicing the Radio 4 discipline of "One song to the tune of another") I'm still scratching my head to find a 10.7.10.7 tune which I might know from some other context. Any suggestions?
