Okay, here’s a dumb question- bear with me please. When do we say the Antiphons? Wherever an asterisk (*) appears? Or in between the Psalms (Antiphon, Psalm, Antiphon, Psalm, Antiphon)?
Generally speaking, you recite the antiphon first, then the psalm, the Glory to the Father and repeat the antiphon.
And do we make the Sign of the Cross whenever a cross (+) appears? Is it permissible to use any reverent tune for the Hymns?
Don’t know what you’re referring to or what edition of book you’re using but if you’re seeing a * and a dagger, you may have an edition that tells you when to use the flex or mediant tones. You would only use these when chanting the psalms.
The sign of the cross is made at the following points:
At “Lord, open my lips”, made with the thumb on the lips (“small” sign of the cross)
“Large” sign of the cross at the following:
“God, come to my assistance.”
The Gospel canticles “Blessed be the Lord, the God of Israel”, “My soul proclaims the greatness of the Lord”, and “Lord, now you let your servant go in peace.”
The concluding blessing, “May the Lord bless us, protect us from all evil,” “May the all powerful Lord grant us a restful night.”
As for the hymns, you can use any tune that fits the given meter or just recite. Do not omit.
