AUBURN — The Androscoggin Valley Community Orchestra and the Augusta Symphony Orchestra will present a concert of works by Richard Wagner, Tchaikovsky and Johann Nepomuk Hummel on March 26-27 in Manchester and in Auburn.

Julie Schubert-Cowan, who has been a member of both orchestras since 2004, will be featured as trumpet soloist for the Hummel concerto.

A veterinarian by profession, trumpet playing has been a passion for Schubert-Cowan from an early age.

A resident of Bethel, she is a former member of the award-winning Plymouth Centennial Educational Park bands and orchestra, The Kalamazoo Concert Band, Sturgis Wind Symphony, Northeast Kingdom International Wind Symphony, Vermont Brass Ensemble and Mahoosuc Concert Band. She has also played with the Berlin Jazz Band and various pit orchestras.

Hummel wrote his Trumpet Concerto in E Major for Anton Weidinger, Viennese trumpet virtuoso and inventor of the keyed trumpet. It was written in December 1803 and performed on New Year’s Day 1804 to mark Hummel’s entrance into the Esterhazy court orchestra as Joseph Haydn’s successor.

The Symphony No. 6 in B minor, Op. 74, “Pathetique,” is Tchaikovsky’s final completed symphony written between February and the end of August in 1893. The composer led the first performance in 1893, nine days before his death.

Through the years, there has been speculation about the Russian title of the symphony. It means “passionate” or “emotional,” not “arousing pity.” Tchaikovsky specialist David Brown suggests that the composition deals with the power of fate in life and death.

The “Siegfried Idyll,” by Wagner, is a symphonic poem for chamber orchestra. Wagner composed the piece as a birthday present to his second wife after the birth of their son, Siegfried, in 1869. It was first performed on Christmas morning of 1870 by a small ensemble on the stairs of their villa in Switzerland. It is said that Wagner’s wife awoke to its opening melody that day.

Wagner originally intended the “Siegfried Idyll” to remain a private piece, but he was forced to sell the score to a publisher in 1878.

The combined AVCO and Augusta Symphony Orchestra are under the direction of Paul Ross. He is cellist with the Portland String Quartet, conductor of the Brunswick Regional Youth Orchestra and the Kennebec Valley Community Orchestra, and a member of the music faculty of Colby and Bowdoin colleges.

Concerts will be at 7:30 p.m. Saturday, March 26, at Hope Baptist Church, 726 Western Ave., Manchester; and at 3 p.m. Sunday, March 27, at High Street Congregational Church, Auburn. Tickets are $10 for adults. Students and children admitted free.
