Érard Frères 1805


Date: 1805

Origin: Paris

Serialnumber: 6115

This very rare and elegant square piano was made by Érard Frères in Paris in 1804/1805. The case with its original legs is made in mahogany with inlays and original ormolu decorations around the case and legs.

The nameboard is signed with:

“Érard Frères

Rue du Mail No. 37 à Paris 1805.”

The original keyboard with a compass of 5 ½ octaves (FF – c4) is made in ivory and the instrument has got 4 pedals.

On the soundboard is the typical handwritten signature from Érard with the serial number 6115. By doing the research about the history of the instrument I found out that it was made for the family Cochu.

A very rare and early instrument made by one of the famous instrument builders in the world.

The instrument has undergone only minimal restoration and remains in a highly original state.
