Easter Hymn: “O Filii et Filiæ” • Contemporary setting (SATB)

Pardon my squeaky Soprano notes, but I wanted to demonstrate how it sounds! • A wonderful setting of the haunting “Easter Alleluia” based on a work by Monsignor Jules Van Nuffel.

The “Secret” Prayer

It would be difficult to imagine more holy prayers than the “orations” at Mass: i.e. the Collect, Secret, and Post-Communion. Consider the Secret Prayer for Trinity Sunday: “Hallow, we pray thee, Lord our God, by our invocation of thy holy name, this sacrificial offering, and work upon us until we too become an eternal offering to thee: through our Lord.”

“Music List” • 4th Sunday of Lent

Some have expressed interest in perusing the “ORDER OF MUSIC” I prepared for the 4th Sunday of Lent (30 March 2025). If such a thing interests you, feel free to download it as a PDF file. The Propers are particularly beautiful, especially the INTROIT (“Lætare Jerúsalem”).

Communion Chant (4th Sunday of Lent)

You can download the Communion Chant for the 4th Sunday of Lent (Year C). Its opening phrase calls to mind the authentic version. I have created a rehearsal video to assist volunteer choirs.

When to Sit, Stand and Kneel like it’s 1962

There are lots of different guides to postures for Mass, but I couldn’t find one which matched our local Latin Mass, so I made this one: sit-stand-kneel-crop

The Funeral Rites of the Graduale Romanum

Lately I have been paging through the 1974 Graduale Romanum (see p. 678 ff.) and have been fascinated by the funeral rites found therein, especially the simply-beautiful Psalmody that is appointed for all the different occasions before and after the funeral Mass: at the vigil/wake, at the house of the deceased, processing to the church, at the church, processing to the cemetery, and at the cemetery. Would that this “stational Psalmody” of the Novus Ordo funeral rites saw wider usage! If you or anyone you know have ever used it, please do let me know.

Antiphons Don’t Match?

A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music).
