The last piano Frederic Chopin played and where he composed music is being restored to its original mid-19th century condition.

Restorer Paul McNulty is spending days at the Chopin museum in Warsaw filling in some cracks in the soundboard and putting in wire strings like the ones used by the piano’s Paris manufacturer in 1848.

Texas-born McNulty says this is the best preserved piano in the world  but since the strings were changed for modern ones in the ’50s, the tone was destroyed.

McNulty believes the work will bring it as close as possible to the sound that Chopin heard.
