Musicologist Peter Wollny chanced upon the manuscripts in 1992 and authenticating them took half of his lifetime

The best fictional detectives are famed for their intuition, an ability to spot some seemingly ineffable discrepancy. Peter Wollny, the musicologist behind last week’s “world sensational” revelation of two previously unknown works by Johann Sebastian Bach, had a funny feeling when he chanced upon two intriguing sheets of music in a dusty library in 1992.

Archive director in Germany says ‘missing piece of puzzle’ now in place to verify authorship after decades of research

Two long-lost organ pieces by Johann Sebastian Bach have been performed in Germany, roughly 320 years after the composer wrote them as a teenage music teacher.

Entitled Chaconne in D minor BWV 1178 and Chaconne in G minor BWV 1179, the pieces were added to the official catalogue of Bach’s works on Monday and played in public for the first time in three centuries inside Leipzig’s St Thomas Church, where Bach is buried.
