Recently identified musical pieces by Johann Sebastian Bach have been presented and played in the European nation for the premiere performance in three hundred twenty years.
Germany's Culture Minister the cultural official described the finding of the pair of works a "important event for the world of music".
They initially attracted notice of a musical scholar in 1992 when he was organizing the composer's papers at the Brussels archive.
The organ works - the Chaconne in D minor and G minor composition - were undated and unsigned. Mr Wollny spent the following three decades working to verify the authorship of the pieces.
They were played at the St Thomas Church in the German city, where the composer is buried and where he was employed as a church musician for twenty-seven years.
The compositions were performed by organist from the Netherlands the musical performer, who said he was honored to be able to present them for the first time in three hundred twenty years.
He said the compositions were "exceptionally well-crafted" and would be "an important addition for modern musicians, as they are also appropriate for reduced-scale organs".
They are believed to have been composed at the beginning of Bach's professional life, when he was working as an organ teacher in the municipality of the German town in central Germany.
The scholar, who is now the leader of the Bach research center in the city, said they demonstrated several qualities unique to the composer.
"In terms of style, the compositions also contain elements that can be observed in Bach's compositions from this period, but not in those of any other composer," he said.
They are considered to have been written down in the early eighteenth century by one of Bach's pupils, the historical figure.
At a revealing of the pieces, Mr Wollny said he was "almost completely confident that the composer had composed the two compositions" and they have now been incorporated into the authoritative listing of his compositions.
