More Sunday Afternoon Concerts in the Dome, Mt. Wilson Observatory

Classical concerts in the clouds! Under the magnificent vaulted dome of the 100-inch telescope, Mt. Wilson Observatory’s Sunday Afternoon Concerts in the Dome have resumed with a limited engagement this summer.

This year there will be a brief season of two concerts, to be held on Sunday August 1 and Sunday September 5, 2021—both dates with two performances each—at the Mount Wilson Observatory, the scientific marvel in the mountains above Pasadena.

As in the last three years of this series, Artistic Director Cécilia Tsan curates thoughtful musical adventures. On Sunday, August 1, the concert opens with Franz Schubert’s beautiful Salve Regina in A major, D. 676, for soprano and string quartet. Then follows the World premiere of Le Lys et la Lyre (The Lily and the Lyre) for soprano and cello, a piece written for Ms. Tsan by French composer Éric Tanguy to a poem by renowned poet and French Academy member François Cheng—a triple shot of French spirit. The program concludes with one of Schubert’s iconic works, his String Quartet No. 13 in A minor, D. 804, Rosamunde.

Esteemed performers for the August concert include Elissa Johnston, soprano, Ambroise Aubrun and Henry Gronnier, violins, Alma Fernandez, viola, and Cécilia Tsan, cello. The concert’s hour-long performances are at 3:00 PM and 5:00 PM (same program), with an artist reception, including refreshments, at 4:00 PM. In addition, concert-goers will be treated to an exhibition featuring unique astronomical artifacts, drawings, and photographs from the Observatory’s collection.

Seating inside the historic dome is limited. Tickets cost $50 each and are available for purchase in advance (highly recommended) or at the door, given availability. Concert attendees must be fully vaccinated. Children under age 12 are not permitted. Access to the dome performances is via a 53-step staircase. Mount Wilson Observatory sits at a mile-high elevation so the air is noticeably thinner. There is no ADA-compliant access. For more information on Sunday Afternoon Concerts in the Dome, please visit

All proceeds go to support the Mount Wilson Institute in its mission to preserve, protect and promote the Observatory and the accomplishments there. Poised for rediscovery, the grounds of the legendary observatory—founded in 1904 by astrophysical pioneer George Ellery Hale—are open for free to the public year-round.

More about the Sunday August 1, 2021 Concert:

Franz Schubert, Salve Regina in A major, Op. 153, for soprano and string quartet

In 1816, Schubert composed several liturgical works: a Latin Mass, a German and a Latin Salve Regina, a Stabat Mater, two Tantum Ergos, and a Magnificat, plus a Requiem in 1818. Previously, in 1814, he met a young soprano named Therese Grob, the daughter of a local silk manufacturer. Several of his songs, including Salve Regina and Tantum Ergo, were composed for her voice. In 1819, he wrote another Salve Regina, this one in A major, and began to work on the great Mass in A-flat, which took him nearly three years to complete. Schubert composed seven Salve Reginas between 1812 and 1824. This one, No. 5, is considered the “jewel among the Salve Reginas.” It is often played by a string orchestra but this soprano and string quartet version beautifully expresses the deep emotional content of the piece.

WORLD PREMIERE: Éric Tanguy, Le Lys et la Lyre (The Lily and the Lyre) for soprano & cello, based on a poem by François Cheng

François Cheng, poet and friend of Ms. Tsan’s parents, who also emigrated from China to Paris in the 1950s, is the only writer of Asian descent to become a member of the venerable Académie Française, the most prestigious honor for a writer in France. In his book, Five Meditations on Death, he quotes a poem that he rendered in calligraphy for Cécilia, and mentions the possibility of Éric Tanguy writing music for his verse. Cheng’s vision became a reality in 2019-2020 when Tanguy composed this piece for soprano and cello, dedicated to Cécilia. It was to have been premiered at Mount Wilson last season, but history had other ideas.

Franz Schubert, String Quartet No. 13 in A minor, D. 804, Rosamunde

Beginning in 1824, Schubert turned from the composition of songs to concentrate on instrumental chamber music, composing this String Quartet in A minor, String Quartet No. 14 in D minor, Death and the Maiden, Octet in F major, D. 803, the piano duets, Grand Duo, and Divertissement a la Hongroise, as well as the Sonata in A minor for Arpeggione and Piano, D. 821. Schubert dedicated the Rosamunde to Schuppanzigh, the first violinist of the string quartet appointed by Beethoven. The early months of 1824 were unhappy; Schubert was ill, penniless, and plagued by a sense of failure. In a letter to one of his friends, he wrote of himself as “the most unfortunate, the most miserable being in the world. Think of a man whose health will never be right again, and who from despair over the fact makes it worse instead of better.” And yet during these months he composed those masterly chamber works. Schuppanzigh himself played in the premiere performance of the Rosamunde Quartet. This masterpiece has become one of the most beloved pieces of the string quartet repertoire.

Éric Tanguy, Composer

Born in Caen in 1968, Éric Tanguy is one of the most performed French composers in the world. Named “Composer of the Year” by the Victoires de la Musique Classique in 2004 and 2008, he studied under Horatiu Radulescu, Ivo Malec, Gérard Grisey, and Betsy Jolas at the Conservatoire National Supérieur de Musique in Paris.

His catalogue contains over one hundred compositions, ranging from solo works to concertos, vocal works and symphonies, performed by many of today’s greatest conductors (Lionel Bringuier, Semyon Bychkov, Seiji Ozawa, Michel Plasson, Esa-Pekka Salonen, etc.), soloists, and chamber music groups. In 2001, Mstislav Rostropovitch premiered Tanguy’s Cello Concerto No. 2 in France before bringing the work to the United States, performing in Boston and at Carnegie Hall with Seiji Ozawa and the Boston Symphony Orchestra.

His Trio for Violin, Cello, and Piano premiered at Radio France with Marie-Joseph Jude, Stéphanie-Marie Degand, and Cécilia Tsan (who commissioned the work), and was later performed in 2011 by the Pantoum Trio during the Jacaranda Music Festival in Los Angeles.

In January 2014, Paavo Järvi conducted the premiere of Tanguy’s symphonic work Affettuoso with the Orchestre de Paris. In December 2015, Matka — an orchestral work commissioned by Jyväskylä Sinfonia and Ville Matvejeff — premiered with the support of the Kone Foundation to mark the 150th anniversary of the birth of Jean Sibelius. In February 2016, Esa-Pekka Salonen conducted three performances of Affettuoso with the Los Angeles Philharmonic at the Walt Disney Concert Hall, and, in November 2017, Pierre Génisson and the Orchestre Royal de Liège premiered Tanguy’s Clarinet Concerto. The works of Éric Tanguyhave been published by the Éditions Salabert since 1989, and many of these have been recorded (Decca, Erato, Naïve, Transart, Intrada, Ohems Classics, and Genuin).

Elissa Johnston, Soprano

Since its founding in 1904 by astronomer and visionary George Ellery Hale, Mount Wilson Observatory (MWO) has played host to some of the most important discoveries in modern astronomy. Located on Mount Wilson, a 5,710-foot (1,740-meter) peak in the San Gabriel Mountains of the Angeles National Forest, near Pasadena California, MWO features the Snow Solar Telescope (the mountain’s first installation, the largest in the word at the time), its 60-inch telescope (the world’s largest operational telescope from 1908 to 1917) and the 100-inch Hooker telescope (which featured the world’s largest aperture from 1917 to 1949). Mount Wilson Institute has independently operated and maintained the Observatory since 1989 under a long-term agreement with the Carnegie Institution of Washington. For more information, please visit,


The 100-inch telescope is the instrument with which astronomer Edwin Hubble discovered our place in an expanding universe and so expanded our comprehension. The dome for the telescope—designed by Chicago architect D.H. Burnham—is a 20th century temple to science whose acoustics rival the great cathedrals of Europe and provides a unique setting for this ambitious music series. 

Albert Einstein wrote that, “There exists a passion for comprehension, just as there exists a passion for music.” This extraordinary venue, a monument to the pursuit of comprehension, energizes that passion for music.
