“...candescent suns by day...”
- The Question, by Theo Dorgan

The Question
by Theo Dorgan

When the great ships come back,
and come they will,
when they stand in the sky
all over the world,
candescent suns by day,
radiant cathedrals in the night,
how shall we answer the question:

What have you done
with what was given you,
what have you done with
the blue, beautiful world?

About Illuminati

Tony Thornton began Illuminati Vocal Arts Ensemble in the fall of 2013, with a mission to create a professional-caliber vocal arts ensemble with the heart and dedication of an amateur chorus. Dr. Thornton is well acquainted with professional ensembles, as you can see from his biography.

The Illuminati Vocal Arts Ensemble is beginning to realize Tony’s vision. A unique chamber chorus, we draw our volunteer singers from throughout Massachusetts and beyond. We have received rave reviews from audiences and newspapers, and have earned the respect of area cultural institutions.

The ensemble performs choral miniatures and masterworks from all periods and styles, and collaborates with other community/professional organizations.

“Performances at the level of Illuminati's give the listener a clear window into the composer's soul.” - Clifton Noble Jr, The Republican, Oct. 15, 2016

In our our sixth season, we will offer three programs exploring some of the enduring forms of choral music, culminating in a world premiere in June of "A Passion for the Planet" by the noted local composer Geoffrey Hudson, a work that holds up the mirror of art to the daunting challenge of climate change. For this exciting event we will be joined by members of other area ensembles and The Young People's Chorus.

Our 2018-19 season begins with performances of two of the greatest German choral works of the 19th Century - the popular Mass No. 2 in G major by Franz Schubert, composed in 1815; and the Mass in E-Flat Major by Josef Gabriel Rheinberger, composed in 1878. Though separated by time they are similar in affect - each is a work of beauty featuring moments of irrepressible joy.

Schubert, a prodigy, wrote his Mass in G when he was only 18. Even so, it is both simpler and gentler than his first Mass (D 105 in F major). Though it was so little noted in his lifetime that it was not published until after his death (and a rival composer even passed it off as his own), it has become by far the most popular of his short masses, and a staple of the choral repertoire.

Rheinberger was a respected composer of organ music with little experience with the choral genre when was appointed Director of the Court Chapel Choir in Munich in 1877. He at once began a serious study of vocal polyphony. The result, his 1878 Mass in E-Flat Major, was recognized immediately as a work of genius. A year after its completion, it was granted the prestigious Gregorius Medal by Pope Leo XIII. The prominent 19th-20th century critic Otto Ursprung has called it the “most beautiful, pure vocal music of the 19th century.” It reflects Rheinberger's approach, as later recounted to a student - ‘Music without singability and beauty of sound has no legitimacy ... Music is basically an outpouring of joy and even in pain knows no pessimism.’

We round out our program with Mozart's brilliant and influential motet Ave verum corpus (K. 618), "Hail, true body." Mozart wrote it just six months before his death, as he took a break from composing Die Zauberflöte to visit his wife Constanze, who was pregnant with their sixth child. Perhaps in honor of her condition, it is a gentle and tender work, almost a lullaby.

Seating at Edwards Church is limited, and we expect to sell out. We recommend you purchase tickets in advance through the form below. Season passes are also available, which offer preferred seating and waived internet service fees.


Entrance into the ensemble is by audition only (see audition process below). Dr. Thornton seeks singers with considerable choral experience. While perfect sight reading is not required, all singers must fully prepare repertoire before the first rehearsal. Illuminati makes music from the beginning.

Dr. Thornton is building an ensemble with a beautiful, communicative sound: tall, warm, vibrant, and round vowels; a wide dynamic palette; an inner rhythmic drive; and in-tune and balanced resonance. In the soprano section he is looking for lyric, energized purity; in the alto section a rich, full sound; in the tenor section a lyric, high/forward, yet warm sound; and in the bass section a rich baritone sound with forward placement that is not overly dark.

If you are interested, please complete the form here and we will email you an audition confirmation with possible times.

Audition Process:
The audition takes approximately ten minutes. Singers will be asked to perform scales using a variety of articulations (legato, staccato, and marcato) and dynamics to demonstrate color, range, quality, and flexibility. A segment of the audition will emphasize sight-reading and tonal memory (with accompaniment). Finally, each singer should prepare his or her vocal part of this PDF excerpt from BWV 76 (Die Himmel erzählen die Ehre Gottes, measures 20-36 only). The excerpt will be sung without accompaniment. Singers should perform as close to quarter=96-100 as possible. German is preferred, but a neutral syllable may be used.
