TOPSHAM — The Oratorio Chorale opens its 39th season with the music of Schubert and Mozart, a program combining the physical color of sound with passionate expressionism, a news release said.

Concerts will be held on Saturday, Nov. 17, at 7:30 p.m., at Orion Performing Arts Center, 50 Republic Ave., Topsham, and Sunday, Nov. 18, at 3 p.m., Sacred Heart Church, 326 Main St., Yarmouth.

Featured are the Schubert “Mass #6 in E flat,” three motets by Mozart and “Eine kleine Nachtmusik.” The chorale will perform with the Maine Chamber Ensemble, under the baton of director Peter Frewen. Solo roles in the Schubert will be performed by members of the chorale.

Franz Schubert’s “Mass in E flat” is one of a series created by the composer in his final years. In fact, the “Mass” wasn’t performed until a year after his death. In his musical notes, Frewen points out that Schubert was extremely prolific at this time. In addition to the Mass, he also created an “enormous” symphony, a string quartet, three piano sonatas, and more.

The chorale will also perform three motets by Wolfgang Amadeus Mozart. The hymn “Sancta Maria” and “Misericordias Domini” were both composed when the young Mozart was at the court in Munich. Mozart, like Schubert, was quite productive during the final year of his life, 1791. Along with the “Requiem,” he composed the “Ave Verum Corpus,” the third motet on the Oratorio’s program. Frewen describes it as “the perfect miniature.” Rounding out the Mozart portion of the program will be “Eine kleine Nachtmusik,” composed in 1787.
