Boulder Chamber Chorale and Chamber Orchestra join forces Friday
By Peter Alexander Oct. 4 at 12:10 p.m.
Conductor Bahman Saless and the Boulder Chamber Orchestra (BCO) will join together with Vicki Burrichter and the Boulder Chamber Chorale to perform one of the least known of Mozart’s major works Friday (7:30 p.m., First United Methodist Church; details below).
The C Minor Mass is, alongside the Requiem, one of two major choral works that Mozart left unfinished. Probably because it was never finished, and also because it is a difficult piece to put together, it is not performed very often.
Mozart began this very large-scale setting of the Ordinary of the Mass—those portions that are performed year-round as opposed to texts that are specific to individual days of the year—in 1782, soon after his marriage to Constanze Weber. Mozart said he started the Mass in honor of his marriage, but he never finished the work.
The opening Kyrie movement and the Gloria were completed, as were two sections of the Credo, as well as the Sanctus and Benedictus. The remainder of the Credo and the Agnus Dei text were never written. On the basis of the completed movements, a full Mass would have been an extensive work.
Mozart and Constanze visited the composer’s father Leopold in Salzburg in October of 1782, with the completed portions of the Mass in hand. At least some portions of Mozart’s score were performed as part of a service in Salzburg, including Constanze singing Et incarnatus est, a beautiful and difficult soprano solo. What else was performed is unknown, and Mozart never wrote another note of the Mass after the visit to Salzburg.
One theory is that Mozart had started the mass as a gesture to his very religious father, who had not approved of the marriage with Constanze. Having mollified the testy Leopold during his visit, he had no reason to write more, as there were no performance possibilities for a large-scale Mass setting in Vienna, due to the policies of the Austrian Emperor Joseph II.
In any case, the Mass in C minor falls at a transition point in Mozart’s life, at the time not only of his marriage but of his move to Vienna and his emergence as an independent composer. It also represents a new development in his musical style, which came about from his study of the Baroque masterpieces of Bach and Handel. The Mass contains several large-scale fugues and a few movements for double-chorus, which add to the complexity and difficulty of the choral parts.
“Every movement has a different challenge,” Burrichter, who rehearsed the chorus, says. “The double choruses certainly are challenging, in terms of listening to each other, and the fugues are extremely difficult and long. But in spite of the difficulties, we’ve all been thrilled with learning it. As Mozart is, it’s so beautifully melodic, it’s so emotionally powerful, and it’s a treat.”
Saless, who will conduct the performance, shares Burrichter’s appreciation for Mozart’s music. “It’s a beautiful piece, and it has incredibly gorgeous arias,” he says.
Among the arias, Burrichter points specifically to the one that Mozart wrote for Constanze. “The Et incarnatus est, one of the great soprano solos, is just one of the best things he ever wrote,” she says. “It’s really stunning!”
To sum up the Mass, Burrichter particularly likes to quote Patrick Mackie, who wrote in his book Mozart in Motion that “The C-Minor mass is . . . a sort of total statement on everything music could be . . . (It) has a surging monumentality and a giddy, athletic zip.”
The concert will open with the Colorado premiere of Summation, a brief piece for chorus and orchestra by composers Jim Klein and Ian Jamison. The performance by the BCO was commissioned by Klein, a successful businessman and entrepreneur who works as a visual artist in a studio outside Greeley and owns an art gallery in Scottsdale, Arizona.
“We’re really delighted to showcase music by local Colorado composers,” Saless says. “It’s obvious this piece was inspired by a spiritual experience.”
Klein explains that source of inspiration in his program notes, where he writes “On my daily early morning walk down our farm lane over the decades, I have often asked the question, ‘Who am I?’” One day, while walking with his dog, he writes that the answer came to him in a text that begins “God is in me.”
WIth that thought in mind, he worked with Jamison to express the text in music. “Hopefully,” he writes, “this internal investment will pass on for future generations.”
In addition to the Boulder performance Friday, the program will be presented at the University of Northern Colorado Commons in Greeley at 3 p.m. Sunday. Links for the purchase of tickets are listed below.
