Sam Haywood: Fantasy Impromptu on Chopin's Pleyel

Chopin, who preferred Pleyel pianos above all others, chose this piano shortly after it had been completed in January 1848.

Chopin almost certainly used it for his last concert in Paris in February 1848. He brought it with him to England in April and gave his first London concert on it. 

The instrument is part of the Cobbe Collection at Hatchlands Park.
