The music for the responses and psalms for the Catholic Lectionary is tuneful and easily remembered: so no need to rehearse the congregation!
For the Cantor we have made them as accessible as possible by setting the text under the music rather than using the pointing system. This clearly and quickly indicates where the notes change.
But the thing that is really going to make this new collection of Psalms and Gospel Acclamations take off is the recording of every psalm and gospel acclamation so that Cantors can learn them at home.
