THE city’s largest choir is to perform two popular classical works in the spectacular setting of Durham Cathedral.

Durham Choral Society, which boasts around 150 members, will stage two pieces by Mozart in their concert on May 20.

The choir will first stage Mozart’s Requiem Mass in D Minor commissioned in 1791 by Franz, Count of Walsegg on the death of his wife.

However it was left unfinished when Mozart died in December of that year and Constanze, Mozart’s wife, gave the task of completing the score to Joseph Eybler who was able to embellish part-written sections such as the Dies Irea but could not rise to the challenge of composing from scratch.

Constanze then asked Franz Xavier Sussmayer to complete the task but his full contribution is still unknown.

Sussmayer’s completed score is dated 1792. In the 19th century, Mozart’s Requiem was used at the funeral or memorial services for many leading composers and musicians including Haydn, Beethoven, Schubert, Chopin, Rossini, and Berlioz.

The society, which was founded in 1946, will also perform the composer’s Solemn Vespers, a sacred work, also known as the Vesparae Sollones de Confessore, which was composed in 1780 for liturgical use in Salzburg Cathedral and was Mozart’s final choral work composed for the cathedral. The title “de confessore” was not Mozart’s own, but was added to the score later in different handwriting, possibly to distinguish it from Mozart’s previous composition Vesperae de Dominica from the previous year.

The concert will take place in Durham Cathedral on May 20 at 7.30pm.

Tickets, priced £18 and £10 with a reduction for concessions and half price for children, are available from the Gala Theatre Box Office or on the door.
