Wolfgang Amadeus Mozart
(1756-1791)

Mozart’s religious music is actually the least important part of his output. His relations to the church were troubled, and unlike Bach he lived in a milieu where the profoundest ideas of the time were not practiced in church. At the same time there are remarkable, profound church works that will never be forgotten. While in the service of the unpleasant and autocratic Archbishop Colloredo, Bishop of Salzburg, Mozart bridled at his official duties and wrote some of his most remarkably ho-hum works. His very last Salzburg liturgical work, the Vesperae solennes de Confessore (Solemn Vespers) K. 339, is, however, a masterpiece and is a foreshadowing of the two great unfinished religious works of his Vienna period, the Mass in C Minor and the Requiem.

One of two settings Mozart made of this service, K.339 was intended for the special celebration of an undisclosed saint’s day (the “confessor” of the title). Its six movements would have been interspersed with readings and other formalities appropriate for a festive religious occasion. The text consists of five Psalms and the Magnificat canticle that concludes every Vespers service. As required by Mozart’s conservative employer, Archbishop Colloredo, each Psalm is set as a continuous movement, as opposed to being divided into separate arias, ensembles, and choruses in the operatic style invading church music at that time.

The work shows all of the stylistic tendencies of the Austrian Baroque, bright and shining brilliant Allegros, and an impressive nod to Austrian liturgical counterpoint as practiced by the early eighteenth century composer, Fux. Just before the final dazzling Magnificat is an inward and luscious Laudate Dominum for soprano and chorus, a work beautiful enough for a place in any of his operas but somehow breathing an inward spiritual air perfectly appropriate to a church service. After his discovery of Bach and Handel, both of whom were represented in the library of Baron von Swieten in Vienna, Mozart would delve more deeply into the possibilities of liturgical counterpoint, but this wonderful work is an important monument on that particular journey.

Wolfgang Amadeus Mozart
(1756-1791)

After a brief stay in Paris, the 23-year-old Wolfgang Amadeus Mozart (1756 – 1791) returned to Salzburg in 1779 to serve as court organist for the Archbishop Colloredo. The working conditions seemed at the time quite favorable for Mozart. His duties included playing the organ in the cathedral, at court and in the chapel, and instructing the choirboys. He seemed to enjoy his new duties and carried them out enthusiastically. From 1779 to 1780 he composed the “Coronation” Mass in C, K. 317, the Missa Solemnis, K. 337, as well as two vespers settings and the Regina Coeli, K. 276. Among these sacred works, the Coronation Mass has achieved a status and popularity that approaches that of the Requiem in D Minor (K. 626) and is among his best-loved Salzburg compositions. The nickname derives from the tradition that Mozart composed the mass to fulfill a vow to commemorate the crowning of the miraculous image of the Virgin Mary in the pilgrimage church of Maria Plain near Salzburg. It is more likely that the nickname was given 12 years later at a performance conducted by Salieri on the occasion of the coronation of Leopold II.

This mass retains its musical appeal due to its richness of contrast, the melodic strength of musical ideas from movement to movement with careful attention to detail, and a variety of musical ideas throughout. The Kyrie is in the standard “A-B-A” format; however, Mozart breaks the tradition of the typical fast-slow-fast pattern and reverses it to slow-fast-slow. The “B” section usually is reserved for the Christe eleison text; however, those words are uttered only twice and in C minor! A solo quartet is infused throughout the mass and is showcased during the Benedictus. Text painting is especially evident in the Credo, such as at the et incarnates est, in which the violins depict the descent of the holy Spirit, the three loud nail hammering-like pulses just before the Crucifixus and the return of the joyous opening Credo theme and tempo at the et resurexit. All the movements are in C major except for the Agnus Dei, which is in F, but returns to C at the Dona nobis with the same thematic material as in the fast section of the Kyrie. The soprano solo of the Agnus Dei foreshadows “Dove sono,” the countess’ aria in Le nozze di Figaro (K. 492).

The Sanctuary Choir of Holy Trinity Catholic Church has been under the direction of J. C. Terpstra for the past 20 years.  The thirty-five-member choir sings choral music from a variety of periods and styles and has worked continuously to spread God’s Word through their gift of music.  They are the principal choir for the parish and are responsible for leading the congregation in song and providing special choral music for weekly masses and holy days. In addition to the regular music liturgy for the mass, the Sanctuary Choir presents a Christmas Concert during Advent, performs an annual Memorial Concert near the feast of All Soul’s Day, and most recently performed Dubois’ Seven Last Words of Christ during Lent. The choir, soloists, and orchestra have most recently performed Handel’s Dettingen Te Deumand Messiah, Mozart’s Requiem,Missa Solemnis in C minor, and several of his smaller choral works, Rutter’s Requiem, Faure’s Requiem, Cherubini’s Requem Mass in C minor, and Lauridsen’s Lux Aeterna.
