Wishing you all a blessed Corpus Christi, here are some recordings and practice videos of some of the English chant propers found in Lumen Christi Simple Gradual.
These antiphons use the new translation of the Roman Missal as their basis, and are simple enough for the entire congregation to sing, while having enough musical interest and beauty to bear repetition over time, year after year.
Even if your parish will not be singing the proper antiphons of the Mass this year, you can prepare yourself by praying along with the chants that the Church places before us on this most solemn feast of the Most Holy Body and Blood of Christ.
The Lumen Christi Simple Gradual can be ordered here.
