The unfamiliar familiar by Seicento

Baroque Ensemble celebrates it 10th anniversary at the weekend

By Peter Alexander April 21 at 1:30 pm.

Boulder’s Seicento Baroque Ensemble celebrates its 10th anniversary this weekend (April 22–24) performing a piece that is both familiar—and not.

The piece is the Magnificat by J.S. Bach, which as the Magnificat in D is one of the most celebrated works of the Baroque master. But they will not perform that Magnificat, but a lesser known, earlier version in E-flat that has much of the same music, with interesting twists.

Completing the program, titled “Magnificent Magnificats,” are two other settings of the same sacred Christian text, known as the Canticle of Mary. One is anonymous, although previously attributed to the German composer Dietrich Buxtehude, and the other is by the 17th-century French composer Marc-Antoine Charpentier. Performances will be Friday through Sunday in Longmont, Arvada and Boulder.

‘A space of awe and wonder’

Pro Musica brings musical and spiritual insights to Bach’s Mass in B Minor

By Peter Alexander Oct. 24 at 4:10 p.m.

J.S. Bach’s monumental Mass in B Minor is one of the great works in the European musical tradition.

Cynthia Katsarelis, conductor of the Pro Musical Colorado Chamber Orchestra describes it as “a cathedral in both sound and spirit.” She will conduct the Mass in B Minor Friday and Saturday (Oct. 25 and 26) in Denver and Boulder. In addition to Pro Musica, the performances will feature St. Martin’s Chamber Choir, directed by Tim Kreuger, and four soloists: soprano Jennifer Bird, tenor Derek Chester, mezzo-soprano Julie Simson, and baritone Jeffery Seppala.

“It’s certainly a bucket-list piece, for both me and Tim Kreuger,” Katsarelis says. “We’ve talked about this for years, and it was time. There’s something about Bach and particularly the choral masterpieces and the B-minor Mass in particular that is so universal and so touches the spirit and the soul, and connects us to our humanity.”

Katsarelis relates that perception of the Mass to an underlying theme for the current season of three concerts: Social conscience and the human condition. The second concert (Feb. 1 and 2) is titled “Diverse Voices” and will feature music by African-American composers William Grant Still and Gabriela Frank. In March they will present “Composing Climate,” featuring Gwyneth Walker’s Earth and Sky, which has texts from Native American leaders Chief Joseph and Chief Seattle, alongside words by Henry David Thoreau.

Boulder Bach Festival returns to the B-Minor Mass, but differently

Concert performance in Macky Auditorium will not be ‘historically informed’

Conductor Zachary Carrettin and the Boulder Bach Festival return to one of J.S. Bach’s masterworks of their repertoire on Sunday (Nov. 11), the Mass in B minor. But if you heard it the last time they performed the same work, in 2015, you should know this time will be different.

Then it was performed in intimate settings in Boulder and Denver; now it will be performed in Macky Auditorium. Then it was performed by a small chorus and orchestra; now the numbers will be greater. Then there were period instruments; now there are not. Then the soloists were early-music specialists; now they include operatic voices.

In fact, this will be very much a “modern” performance, with no self-consciously historical performance practices. Doing a deliberately non-historical performance seems unusual for an organization devoted to early music, but that decision was influenced both by the large concert hall where it will be presented and by Carrettin’s own philosophy.

“I firmly believe that the acoustic environment, the ensemble size, and the approach that we take with phrasing and tone production and balance should change from concert to concert,” he says.

Its next concert will return to the original focus of the festival by presenting choral works by J.S. Bach with soloists and orchestra. After several concerts featuring music by composers before and after Bach, and introducing various performance styles, the program will comprise four of Bach’s church cantatas: No. 4, Christ lag in Todesbanden; No. 50, Nun ist das Heil und die Kraft; No. 61, Nun komm, der Heiden Heiland; and No. 63, Christen, ätzet diesen Tag.

“All of these works have great arias, beautiful duets, riveting choruses and gorgeous orchestral writing,” Zachary Carrettin, the festival’s artistic director, says. “I love these four works, and I thought they would be fabulous on one program.”

Carrettin will conduct the Boulder Bach Festival Chorus and Orchestra, with soloists Josefien Stoppelenburg, soprano; Abigail Nims, mezzo-soprano; Derek Chester, tenor; and Ashraf Sewailam, bass. “These are four of the greatest soloists we’ve programmed,” he says. “I couldn’t think of a better quartet of individuals to collaborate with our chorus and orchestra.”

Boulder Bach Festival goes exploring in an intriguing concert

Unfamiliar works and an unfamiliar instrument are unexpected treasures

By Peter Alexander

compass-logo-plusThere is a reason that the Boulder Bach Festival (BBF) uses a compass in its logo.

As demonstrated in their 2016–­17 season-opening concert yesterday (Oct. 15), the BBF under music director Zachary Carrettin goes sailing out into Bach’s musical world, looking for new discoveries for players and audiences alike. And usually, like yesterday’s concert, they bring back unexpected treasures.

The performance, given in Boulder’s Adventist Church, was a repetition of a program given Friday evening in St. John’s Episcopal Cathedral in Denver. Titled “Concertos and Chorales Contextualized,” the program explored the many different ways Lutheran chorale tunes were arranged and used as the basis of larger works in the Baroque period (late 1500s to roughly 1750), and also how Bach’s concertos reflected compositional techniques that had been refined through settings of chorale tunes.

There was music on the program from the early Baroque, starting with a work by the truly obscure Bartholomeus Gesius (1562–1613), through the slightly better known Michael Praetorius (1571–1621), Johann Hermann Schein (1586–1630), and Samuel Scheidt (1587–1654), and culminating with J.S. Bach (1685–1750). (See my preview of the concert here.)

Unfortunately, the space at the Boulder Adventist Church does not lend itself to clarity of the complex counterpoint you find in much Baroque music. This was evident with both the small orchestra assembled for two of J.S. Bach’s concertos, and the Boulder Bach Festival Chorus, which sang several works on the program.

The fault is not with the performers, who sang and played confidently. Carrettin led the program decisively, with a fine sense of style. Nevertheless, works performed from the front of the church were not always as clean as one would wish. Mid- to low-range sounds tended to get murky, and the bass lines were not always clear.


Organist Christopher Holman

The sound is better when the music originates from the choir loft, at the back of the sanctuary. The choir sounded cleaner and clearer from the loft, and the organ, played splendidly by Christopher Holman, was transparent and at times sparkling.

In spite of any acoustic limitations, it was a thoroughly worthwhile and intriguing program, and may well have been more fully satisfying in the Denver venue.

Before the second half of the concert, Carrettin gave a brief talk on how the word Ach (the German equivalent of “Ahh!”) in Bach’s motet Jesu Meine Freude corresponds to similar exhalations in other cultures and spiritual traditions around the world. This both served to make the music, firmly grounded in north German Lutheran religious practice, more universal, and personified the festival’s motto “Across Time, Across Cultures”—the spirit that underlies the adventurous direction of today’s Boulder Bach Festival.

Three parts of the program were particularly pleasing. The anonymous setting of Ach Gott, vom Himmel sieh darein (Oh God, look down from heaven) for organ was a delightful discovery, with rippling runs and a growing sense of pace. As throughout the concert, Holman’s playing brought the music energetically to life.

Of the two concertos, Bach’s Brandenburg Concerto No. 6 was the best instrumental selection on the concert. A string ensemble with violas at the top of the texture runs the risk of being murky throughout, but the smaller ensemble and careful work by the players mostly overcame the danger. The texture was generally transparent.

The playing by viola soloists Aniel Cabán and Tal McGee was particularly lovely in the slow movement, and the finale romped along with great energy.

A word about the cello da spalla (shoulder cello) that Carrettin introduced in this work. He and Renee Hemsing Patten played two interior parts (originally written for viola de gamba) on this unusual and somewhat awkward looking instrument. When heard individually, they projected a solid, clean string tone, and they obviously filled their parts well. To really judge the instruments, it would be necessary to hear one in a solo role—which Carrettin has planned for the BBF concert Dec. 8 in Boulder and Dec. 9 in Longmont.

The final set of the concert comprised three works for the Christmas season, by Michael Praetorius, J.S. Bach, and Gesius. Each work was pleasing, starting with music sung by a chamber choir, and ending with the Gesius sung in surround sound with a rank of singers in each aisle. This was good program planning: ending with the fullest and clearest choral sound of the concert, and yet another fine discovery brought back from the larger musical world.

Boulder Phil will present three works in one

Performances of Bach’s St. Matthew Passion will be a collaboration with several organizations

By Peter Alexander

J.S. Bach’s St. Matthew Passion is at least three different works.

It is a sacred work, written and performed in Bach’s lifetime as part of Good Friday services at the Thomaskirche in Leipzig. It is a concert work that has been performed apart from religious services for most of the 266 years since Bach’s death. And it is a dramatic work, the closest Bach came to writing an opera.

This weekend’s performances by the Boulder Philharmonic, a semi-staged production presented in conjunction with the Boulder Bach Festival, Central City Opera, the CU College of Music and the Boulder Children’s Chorale, will definitely tilt toward the third option. (Performances will be at 7 p.m. Saturday in Macky Auditorium, with supertitles projected over the stage; and at 2 p.m. Sunday in Denver’s Central Presbyterian Church.)

Bach’s score unfolds on different levels: There is a tenor singing the Biblical narration, a baritone singing the words of Jesus, and individuals from the chorus who sing the words of other characters named by St. Matthew; there is a double chorus, which sings large choral movements that introduce and close the work, the words of the crowd, and Lutheran chorales that symbolically represent the reaction of the congregation; and there are aria soloists who sing non-Biblical poetic texts that reflect upon the story.

To these musical events, this performance will add an onstage dramatization, but not in a literal way. “There’s very little that’s literal action,” stage director Robert Neu says. “What we’re trying to do is take it a little bit out of the realm of a traditional concert performance. The piece is very operatic in the way it’s shaped, it’s very dramatic, but given the nature of the piece, you can’t be overly literal about it.”

Boulder Bach Festival comes to Longmont—inspired by Pink Floyd

Program “wanders through a labyrinth of pre-Bach Italian mysticism”

By Peter Alexander

compass-manuscript1J.S. Bach never heard Pink Floyd or visited St. Mark’s Cathedral in Venice, but both play a part in the Boulder Bach Festival’s opening program for their 35th season.

The concert, “Italian Roots,” will be performed at 7:30 p.m. Friday in the Stewart Auditorium at the Longmont Museum in Longmont, and at 7:30 p.m. Saturday in St. John’s Episcopal Church in Boulder (tickets). The program includes music by Heinrich Ignaz Franz Biber, Jacques Arcadelt, Dario Castello, Johann Jakob Froberger, Biagio Marini, Marco Uccelini and Johann Christoph Bach on the first half, and two works by festival namesake J.S. Bach after intermission.

The Longmont performance opens the Bach Festival’s 2015–16 season and “Bach in Longmont,” a series of three concerts in the new Stewart Auditorium. The series also includes educational events centered at the Longmont Museum.

Performers will include violinist Zachary Carrettin, musical director of the Boulder Bach Festival (BBF) and the Bach Chamber Singers, a small ensemble of four singers. Featured guest artists will be soprano Josefien Stoppelenburg, who sang on the BBF performance of the Bach B-minor Mass in February of this year; Matthew Dirst, a Grammy-nominated harpsichordist and renowned scholar; and violinist Michiko Theurer, BBF artist-in-residence.

Carrettin praises the new auditorium in Longmont. “It’s a beautiful acoustic space, and the lobby is very inviting,” he says. “As (people) walk into the hall, they will realize that it’s an intimate hall, but world class nonetheless.” The connection to St. Mark’s Cathedral, which is famous for having multiple choir lofts so that sounds come from different directions, will be in the creative way Carrettin creates similar effects in the intimate auditorium.

“Whether you want to use the ancient term antiphonal, or the 20th-century term stereophonic, we will be placing artists in different parts of the hall,” he says. “That’s an element of the way we are presenting the entire first half of the program, without pauses between pieces. We’ll improvise transitions from one work to another, and sometimes traveling from left to right on stage.

“The idea is to create half of a concert that is sewn together as its own journey. I have to think of the Pink Floyd albums, or the Yes albums, and the way the artists would weave together pieces of music, sometimes bringing back ideas from previously played songs so that by the end of the album the listener feels that they’ve been told a story.”

According to the BBF Web page, that story will be one of “wandering through a labyrinth of pre-Bach Italian mysticism.” What makes it a labyrinth is perhaps the fact that the composers vary from text-book names unfamiliar to most audience members down to the utterly obscure, but Carrettin is happy to illuminate the various corners of the labyrinth.

“It’s not in the program, [but] I decided to open the program with the Passacaglia for solo violin by [17th-century German composer] Heinrich Biber,” Carrettin says. “The Passacaglia, with its repeated bass line and variations, immediately brings the audience into a space of timelessness.”


Caravaggio’s “The Lute Player”

That timelessness sets the stage for the earliest piece on the program, a madrigal by 16th-century Flemish composer Arcadelt. He was so well known in his lifetime that a 1596 painting by Caravaggio, featured on the BBF Web page, shows a lutenist playing one of his pieces. The text, about love and death—like many madrigals—in turn sets the stage for later works on the program.

The next piece returns to the 17th century with a Toccata by Froberger, who was known as a the composer of keyboard suites and descriptive pieces. “Bach was a virtuoso keyboardist and improviser,” Carrettin says, “so Froberger is an opportunity for us to look at other great keyboard composers.

Harpsichordist and scholar Matthew Dirst

Harpsichordist and scholar Matthew Dirst

“Matthew Dirst ,who’s performing [Froberger’s Toccata] is really an incredible, dynamic scholar and author of a recent book called Engaging Bach. He is perfect for bridging the Italian style and Bach, starting with a piece that just plays with the facility of a keyboard instrument.

“As the program progresses, you’ll hear Matthew in various perspectives and lights.”

The rest of the first half plays out with Dirst playing first a sonata for violin and harpsichord by Castello with Theurer; then a set of variations for harpsichord and two violins by Marini, with Theurer and Carrettin; and another piece by Froberger. The first half ends with the Bach Chamber Singers performing music by one of J.S. Bach’s older relatives, Johann Christoph Bach.

Johann Christoph Bach

“He was actually the most known Bach composer before Johann Sebastian, but history doesn’t remember him,” Carrettin says. “This short motet, World, goodnight, is stunningly beautiful, so I think it’s a great way to end the first half.” Like the Arcadelt, this is another piece reflecting on death.

Carrettin describes the first half of the program as “fragments within a dream,” which contrasts with the two very familiar works by J.S. Bach that will be played in full on the second half: the much loved Harpsichord Concerto in D minor, BWV 1052, and a version of the cantata Ich habe genug, BWV82a for soprano—the concert’s final musical meditation on death.

“Dirst will perform the most famous Bach harpsichord concerto,” Carrettin says. “He’ll be just accompanied by string quartet, so you will really get the sound of the harpsichord ringing throughout the hall.”

Soprano Josefien Stoppelenburg

Soprano Josefien Stoppelenburg

Turning to the cantata, Carrettin says “There are several special elements of our performance. One is that we are doing this one per part, featuring Ysmael Reyes on flute. We’ll have two violins one viola, one cello, and one double bass, and Dirst will play harpsichord.

“Soprano Josefien Stoppelenburg, who thrilled audiences in the B minor Mass, will return to sing this. And what’s so special about this performance is that we’re using the rarely performed version that Bach wrote for soprano.”

Bringing together guest artists with local musicians in something Carrettin especially enjoys. “What thrills me is having an internationally recognized harpsichordist, and an internationally recognized virtuoso soprano sharing the stage with expert front-range musicians and young professionals,” he says.

“What I like is bringing together different generations, different life experiences, and artists from different geographical locations. What ends up happening is these paths of discovery and relationships are created. To me that’s as thrilling as the music.”
