Has Beethoven hit a false note?
Sotheby's is auctioning what they claim to be an original Beethoven manuscript of Allegretto in B Minor.
But Beethoven expert Barry Cooper, of Manchester University, claims that the manuscript being sold is not an original, but a copyist’s transcription.
Simon Maguire, head of Musical Manuscripts at Sotheby's, strongly disputes Cooper's claim. We brought them together on the Today programme in an effort to resolve the dispute.
