BERLIN An early piano believed to have been played by Wolfgang Amadeus Mozart has surfaced in Germany and could be worth millions of euros, a radio station reported Wednesday.

Public broadcaster SWR said the instrument was built in 1775 and acquired in the 1980s by piano manufacturer Martin Becker in the southern German city of Baden-Baden from an antiques dealer in Strasbourg, eastern France.

When Becker decided to auction off the fortepiano, a music historian noticed the offer and “had a hunch that it could be the same long-lost instrument that Mozart played whenever he was in Strasbourg,” SWR said.

A historic oil painting in Vienna shows the composer Joseph Haydn, a Mozart contemporary, playing what may be the same instrument.

The fortepiano, built by Christian Baumann, is one of eight known examples.

SWR said auction house Christies confirmed the instruments provenance but the company could not immediately comment on the report when contacted by AFP.

Experts said the piano could be worth millions if its illustrious pedigree is established. - AFP
