Recently identified musical pieces by Johann Sebastian Bach have been presented and executed in the central European country for the premiere performance in three hundred twenty years.
Germany's Culture Minister the government representative labeled the finding of the pair of works a "important event for the world of music".
They originally drew interest of a Bach researcher in 1992 when he was documenting historical musical documents at the Royal Library of Belgium.
The musical compositions - the Chaconne in D minor and Chaconne in G minor - were without dates and anonymous. Mr Wollny spent the subsequent thirty years working to verify the identity of the pieces.
They were performed at the Thomas Church in Leipzig, where the composer is laid to rest and where he was employed as a church musician for over two decades.
The compositions were executed by Dutch musician Ton Koopman, who said he was proud to be able to present them for the initial performance in three hundred twenty years.
He said the compositions were "of a very high quality" and would be "an important addition for modern musicians, as they are also well-suited for more compact instruments".
They are considered to have been composed early in Bach's career, when he was working as an organ instructor in the community of the Thuringian town in central Germany.
The scholar, who is now the head of the Bach Archive in Leipzig, said they exhibited several qualities unique to the musical genius.
"In terms of style, the pieces also contain characteristics that can be found in the composer's creations from that time, but not in those of different artists," he said.
They are thought to have been written down in 1705 by one of Bach's pupils, the musical student.
At a unveiling of the compositions, Mr Wollny said he was "almost completely confident that Bach had created the two compositions" and they have now been added into the recognized inventory of his works.
