I listened recently - on BBC Radio 3 - to a recital on Chopin's own piano

Earlier this year, Alexander Gadjiev joined his fellow Radio 3 New Generation Artists, the period instrument Consone Quartet to realise his dream of playing Chopin on the composer's own 1848 Pleyel piano. Chopin is known to have preferred the soft-voiced Pleyel pianos above all others, describing them as, “the last word in perfection.” It is very likely that this instrument was the one he had kept at his salon at the Square d’Orléans, Paris before bringing it to England in 1848. The piano now forms part of the Cobbe Collection at Hatchlands Park in Surrey
