Corpus Christi Watershed

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.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

Quick Thoughts

    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.

Random Quote

“Only against this background, of the effective denial of the authority of Trent, can one understand the bitterness of the struggle against allowing the celebration of Mass according to the 1962 Missal after the liturgical reform. The possibility of so celebrating constitutes the strongest, and thus (for them) the most intolerable contradiction of the opinion of those who believe that the faith in the Eucharist, as formulated by Trent, has lost its validity.”

— Cardinal Ratzinger, 2001
