Arizona Tribune - Two newly discovered Bach organ works unveiled in Germany

The two solo organ works, written while Bach was working as an organ teacher in the town of Arnstadt in Thuringia early in his career, first caught the attention of researchers over 30 years ago.

But it is only now that experts have been able to prove they were written by Bach after finally confirming the identity of the person who penned the manuscripts.

The Chaconne in D minor BWV 1178 and Chaconne in G minor BWV 1179 have been added to the official catalogue of Bach's works as of Monday.

They were also performed for the first time in 320 years at the St Thomas Church in Leipzig, where Bach is buried and served as a cantor for 27 years.

In a press conference before the works were performed, Culture Minister Wolfram Weimer hailed the discovery as a "global sensation" and a "great moment for the world of music".

"This is a source of great joy for many, many music lovers around the world," he said.

Bach researcher Peter Wollny first came across the works in the Royal Library of Belgium in 1992, according to the Bach Archive in Leipzig, which documents and researches the composer's life and work.

- 'Missing puzzle piece' -

The manuscripts were undated and unsigned but are thought to have been written in around 1705, when Bach would have been 18 years old.

Wollny was fascinated by the works from the outset because they contained several characteristics that were unique to Bach during that period.

But the identity of the manuscript writer remained a mystery.

Several years ago, experts came across some very similar handwriting in a letter dating from 1729 written by a former pupil of Bach in Arnstadt, Salomon Guenther John.

But since the letter was written 20 years after the manuscripts and the handwriting was not identical, more evidence was needed.

It was only recently that earlier samples of John's writing were found, from around the same period, providing definitive proof that the handwriting was his.

"I searched for a long time for the missing piece of the puzzle to identify the compositions -- now the whole picture is clear," Wollny said.

"We can now say with certainty that the copies were made around 1705 by Bach's pupil Salomon Guenther John."

- 'Lively new repertoire' -

Ton Koopman, the Dutch organist and head of the Bach Archive who performed the works on Monday, said they were "of a very high quality".

"When one thinks of the young Bach or Mozart, it is often assumed that genius comes later in life -- but that is not the case," he said.

"I am convinced that organists worldwide will be very grateful for this virtuoso, lively new repertoire and will perform it regularly in future."

Bach was born in Eisenach in central Germany in 1685 and died in 1750.

Best known for composing the Brandenburg Concertos, he was described by the 18th-century composer Ludwig Van Beethoven as "the immortal god of harmony".

Founded 75 years ago, the Bach Archive has helped to unearth several previously lost works by the composer.

In 2008, an organ piece called "Wo Gott der Herr nicht bei uns haelt" (Where God the Lord does not stay by our side) was found in an auction lot by professors from the Martin-Luther University in Halle.

In 2004, a Bach cantata that had been lost for decades was rediscovered in the papers of Japanese pianist Chieko Hara.
