This is a Bösendorfer piano. The Bösendorfer has been a unique musical item, in that it has three extra keys. This is particular piano a concert grand and it used to belong to the (which?) music society. Since 1828, Bösendorfer has been an Austrian statement of craftsmanship from the Viennese music world, and under the visions of Ignaz Bösendorfer and his son Ludwig Bösendorfer, the ensuing pieces would forever hold the tradition for elegance and uncompromising beauty in the concert halls. The motto of the house of Bösendorfer is: “To give the artists and music lovers of the world an instrument which fulfills their highest expectations.”
