Christ Church Cathedral
Artists: Ensemble Castor; Hélène Brunet, soprano; Rodolfo Richter, violin; Kristina Chalmovska, cello
A fun alternative to Vivaldi’s Four Seasons, this concert pairs concertos for Ensemble Castor’s six musicians with arias and motets by the Venetian ‘Red Priest.’ We welcome the wonderful soprano Hélène Brunet who will unleash her dramatic abilities and virtuosic roulades through arias filled with nature characterizations such as birdsongs, tempests, hunts and pastoral life. Vivaldi uses themes from his Four Seasons in several of his vocal arias and ‘Gelido in ogni vena’ echoes the theme of the first movement of his famed Winter concerto.
“These players never fail to find something to say … lovely, imaginative performances on some sweet-sounding instruments!” – Gramophone, August 2017

PROGRAMME NOTES
Antonio Vivaldi’s Concerto for strings in G Major, RV 151, “Alla rustica” is a ripieno concerto. Written for orchestra without soloists, such works are important antecedents of the symphony. Unlike the famous Le quattro stagioni (“The Four Seasons”), this concerto has no descriptive text to go with it—the phrase “Alla rustica” itself is deceptive, because the music is not at all rustic or provincial but rather a brilliant example of the late baroque style. The concerto was written some time between the mid-1720s and 1730, during which time Vivaldi was also working on his Il cimento dell’armonia e dell’inventione (“The Contest Between Harmony and Invention”), Op.8, including The Four Seasons. Vivaldi both perfected and popularized the concerto form, establishing its standard three-movement, fast-slow-fast structure.
The aria Gelido in ogni vena is from Vivaldi’s opera Farnace, which had its premiere on February 10th, 1727, at the Teatro Sant’Angelo in Venice. The story tells of dynastic quarrels and calculated alliances in ancient Rome. In this aria, King Farnace mourns the supposed death of his son, whose execution he ordered to keep him from falling into the hands of Roman invaders. The sight of his son’s ghost, Farnace sings, freezes the blood in his veins. Vivaldi composed this unique and frightening aria using themes very similar to those of the first movement of “L’Inverno,” The Four Seasons’s winter concerto.
The motet Sum in medio tempestatum belongs to the category “per ogni stagioni” (“for all seasons”), meaning that it can be inserted into almost any Mass or Vespers service. The latest of Vivaldi’s surviving motets, it is preserved in the Dresden collection of sacred music built up by the Bohemian composer Jan Dismas Zelenka (1679-1745); the text for the motet was also set by the famous Neapolitan composer Leonardo Leo (1690-c. 1730). In an opening aria the singer likens the human condition to that of a ship amid stormy seas. The following recitative voices a resolution to renounce the temptations of the world and follow Jesus. This leads to a second, slower aria expressing the singer’s sense of contentment and security in her new-found faith, before a vivacious Allelluia provides a final burst of exuberance. This motet shows Vivaldi at his most galant.
Vivaldi’s Op.1 is an early work, a youthful homage to the style of Arcangelo Corelli (1653-1713). The younger composer nevertheless demonstrates a powerful musical language of his own, one which reappears fully fledged in his famous L’estro armónico (“The Harmonic Inspiration”), Op.3. The most famous piece of Op.1, “La Follia,” is a trio sonata organized as a series of variations. Its thematic material closely resembles that used by Corelli in his own “La Folia” sonata (Op. 5 No. 12). In paying homage to this very famous work by Corelli, Vivaldi brings a new nervous energy to the ancient Iberian theme through an obsessive journey which has little time for lyrical episodes. His virtuosic set of final variations is reminiscent of Corelli’s version but more pounding, impatient and extreme.
Juditha Triumphans is Vivaldi’s only surviving oratorio. He wrote it in 1716 for the musically gifted girls of the Ospedale della Pietà, the Venetian orphanage with which he was associated throughout most of his working life. In 1716, Vivaldi became the Ospedale’s “Maestro di Concerti,” a position that carried the responsibility of writing works to be performed by the girls. In the same year, after a long war against the Turks, Venice obtained a crucial victory in Corfu. The “sacred, military oratorio” Juditha Triumphans was written right after this battle—its biblical subject matter is clearly intended to celebrate the Venetian defeat of the Turks. In the aria Agitata infido flatu, Judith describes her inner turmoil, seeming not to know what to do as she finds herself beloved by her enemy, the Assyrian general Holofernes.
Vivaldi’s twelve concertos of Op. 8 were first published in Amsterdam in 1725; Vivaldi gave them the title Il cimento dell’armonica e dell’inventione and dedicated them to Count Wenzel von Morzin. All twelve concertos in this set are excellent works (although The Four Seasons has come to overshadow the others). Like the first movements of the other concertos, the opening of “La tempesta di mare” is strong and vibrant, featuring driving descending scales; dazzling in its virtuosity, it is a fine specimen of Vivaldi’s art. “La tempesta di mare” (“The Storm at Sea”) and its companion concertos were not—again, unlike The Four Seasons—accompanied by descriptive texts. Instead, the evocative titles of Op. 8 imply a certain emotional state or event; some of the labels appear to have been given as an afterthought to describe already existing music.
Canta in prato, ride in monte is one of Vivaldi’s Roman motets. The singer for whom Vivaldi wrote this piece may well have been one of the principal singers in his operas. This joyful motet is suited to any festival of a saint (who is invoked simply as “Pater Beate” in the recitative). The reference in the first aria to the nightingale, invoked in classical fashion as “Philomela,” calls forth some bird-like warbles, familiar from Vivaldi concertos such as “Il Gardellino.” The second aria stays close to this style with its trilling evocation of rustic flutes.

Rodolfo Richter, violin
A never-ending curiosity, combined with a deep passion for music led British/Brazilian violinist Rodolfo Richter to pursue a diverse career as director, soloist, chamber and orchestral musician, concertmaster, teacher and composer.
Richter is a frequent guest director and soloist around the world, including regular engagements with Tafelmusik (Toronto), Arion (Montréal), Portland Baroque Orchestra, Tesserae (Los Angeles), Seville Baroque Orchestra, the Orchestra of the Age of Enlightenment, the Academy of Ancient Music and B’Rock.
Praised by the international press as ‘one of the most inspirational baroque violinists of his generation’, chamber music has always been at the core of his activities over the years as the leading violinist of many acclaimed groups, such as The Palladian Ensemble, Florilegium, Steinitz Bach Players and Theatre of the Ayre. He often performs in many of the world’s most prestigious concert halls, including London’s The Wigmore Hall, the Concertgebouw in Amsterdam, Konzerthaus Berlin, Musikverein Wien, Sydney’s City Hall, Chicago’s Orchestra Hall and the Alice Tully and Carnegie Halls in New York.
His love for new and old music, particularly early 20th-century chamber music, resulted in the creation of the Richter Ensemble in 2018. With the aim to explore hidden connections between works from different eras, the group often presents programs as varied as Bach/Webern, Schubert/Schoenberg, Rebel/Part or Vivaldi/Reich/Ligeti.
In great demand as a guest concertmaster, Rodolfo has led The English Concert, Concerto Köln, Capella Mediterranea, Pygmaleon, Ex Cathedra, La Nuova Musica, Die Kölner Akademie and the Royal Scottish National Orchestra. He has collaborated with many eminent conductors such as Sir Roger Norrington, Sir Charles Mackerras, Sir Mark Elder, Gustav Leonhardt, René Jacobs, Christopher Hogwood, Trevor Pinnock, Marris Jansons and Pierre Boulez. He is a former concertmaster of the Academy of Ancient Music (2005-2015) and B’Rock (2009-2018).
Richter’s extensive discography includes Bach’s Brandenburg Concertos with AAM (Harmonia Mundi USA) and Vivaldi’s 4 Seasons with B’Rock (Etcetera) as well as the first recording of the complete sonatas by Erlebach (Linn Records) and Guretzkyi’s violin concerto (Chandos). Currently he has embarked with the Richter Ensemble in a project of recording the complete Second Viennese School string quartets on gut strings, thereby proposing a unique interpretation to this repertory.
Recognising the importance of sharing knowledge, Rodolfo is the director of he Early Music Course and Festival at the Oficina de Música de Curitiba in Brazil since 2012. In addition to giving masterclasses all over the world, from 2007-2015 he was Professor of Baroque violin at the Royal College of Music in London.
Richter started his musical education studying counterpoint, harmony and free composition with Hans Joachim Koellreutter. On Koellreutter’s recommendation, he further developed his knowledge of composition by taking private lessons with Pierre Boulez and participating in master classes with Hans Joachim Hespos, Luigi Nono and Elliot Carter. His works have been performed in concert halls and festivals of new music worldwide. He was the musical director of the “Música Nova” concerts series promoted by the Fundação Cultural de Curitiba in Brazil.
Klaus Wusthoff, I-Fu Wang and Pinchas Zuckermann were Richter’s main violin teachers. He later specialized in the Baroque violin with Monica Huggett. Richter was a prizewinner at the prestigious International Early Music Competition for Ensembles in Bruges (2000) and won first prize at the Antonio Vivaldi International Violin Competition (2001).
