Beethoven's own violin has been used in a recording for the first time, according to the Beethoven Foundation.
The violin is engraved with Beethoven's insignia
It was played by German violinist Daniel Sepec on a CD of the composer's violin and piano sonatas.
The instrument, which is engraved with Beethoven's insignia, was in his family's possession until the early 19th Century. Beethoven died in 1827.
The violin ended up in the US and was returned to the Beethoven Foundation in 1995 for a symbolic sum.
It was restored in 1848, and again when acquired by the Foundation.
The new CD comes with a 31-page booklet describing the history of the instrument.
Beethoven wrote 10 violin sonatas and one concerto for violin and orchestra, as well as some unpublished violin works.
