English pianist Joyce Hatto had risen to some prominence over the year preceding her death. Whilst she never played in public, recordings of her performances of works by artists such as Liszt, Schubert, Rachmaninov and Dukas, produced by her husband from a private studio, had her hailed as an unknown genius.
However, an iTunes programme that compares recordings with an online database has thrown her abilities into doubt
A critic for the classical music magazine Gramophone
was surprised to find that, when he loaded into his computer a recording of the pianist playing Liszt, the programme identified it as the work of the pianist Laszlo Simon on BIS Records. The critic tried again, this time using a disc of a Hatto recital of Rachmaninov. Once more, his computer listed it as the work of another pianist, Yemif Bronfman.
The critic was aware of certain rumours doubting Hatto's performances which had been floating around the internet, so he sent the recordings to audio expert Andrew Rose, who confirmed that the soundwaves of the Hatto recitals were identical to the ones of the other pianists.
Gramophone reports how Rose produced a section on his website that allows listeners to compare the pattern of soundwaves of Hatto's recordings with other pianists. When Rose went on to compare the Rachmaninov recital with the Bronfman recording, they also matched.
magazine reports that Hatto's husband has admitted to the scam
