Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

Andrew Leung · January 5, 2017

CTL Dominus Dixit ad Me Download T HAS BEEN A WHILE since I have written here. The life in the seminary has been very busy and the Christmas season has been very intense. As I promised last time, I am going to share more about Fr. Áureo Castro, a priest, composer and music educator of the Diocese of Macau, China. 1

As I mentioned in my last post, I found a collection of choral pieces composed by local composers when I was going through old book in the seminary. One piece that I found in the collection is a setting of Missa de Angelis:

    * *  PDF • MISSA DE ANGELIS (Áureo Castro)

Missa de Angelis has always been the “pop” Gregorian Mass; it is the most widely-known and popular chant Mass setting. Fr. Áureo’s setting alternates the chant melody and the choral parts, which allows both the congregation and the choir to sing. While the internal participation is very important, it is also nice to allow the congregation to participate externally through active singing, especially the Ordinaries of the Mass. While this Mass setting is not the most difficult and complicated, the choral range is pretty wide and can be challenging. Also, you may realize there isn’t a score for the “Agnus Dei” movement; the Portuguese at the end of “Sanctus” actually indicates that Fr. Áureo didn’t compose any choral parts for the “Agnus Dei”.

So, when you are thinking about singing the “pop Mass” next time, consider about using this choral setting. I hope it will add beauty to your worship and make your Missa de Angelis more interesting. Please feel free to leave comments on our Facebook combox.



NOTES FROM THIS ARTICLE:

1   Fr. Áureo Castro was born in 1917 at Pico, on Calendaria in the Azores, Portugal. He came to Macau in 1931 when he was 14 years old and he entered the St. Joseph Diocesan Seminary. He was ordained for the Diocese of Macau later in 1943. He was actively involved in parish ministries and the musical training of diocesan seminarians. In 1951, Fr. Áureo went to Lisbon to further study music at the National Conservatory and he graduated with distinction in music composition. He founded the St. Pius X Academy of Music upon his return to Macau. The institute not only offers music classes, but it also organized public concerts and has invited many internationally famous musicians to Macau. He dedicated his life to the promotion of music and his compositions are widely recognized. He passed away in 1993 at the age of 76.

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

“In everything of any importance at all, Sarum (and all other mediæval rites) was simply Roman, the rite which we still use.”
