Antique Bosendorfer Pianos are musical instruments produced by the Bösendorfer company, an Austrian piano manufacturer established in 1828 by Ignaz Bösendorfer.

Brief history and description

The company was one of the oldest piano manufacturers and was officially named the piano maker to the Emperor of Austria in 1830. Bösendorfer had a well-established history of producing high quality pianos and produced some of the favourite instruments of many classical and contemporary pianists.

Franz Liszt was among one of the earliest artists to be associated with Bösendorfer, along with the twentieth century American composer Leonard Bernstein and renowned jazz songwriter Nina Simone.

Antique Bösendorfer pianos were constructed from spruce jointed together and the company produced one upright piano model and seven variations of grand pianos.

The Imperial Grand is perhaps the best known Bösendorfer piano. Instead of featuring a standard keyboard of eighty-eight keys, the Imperial Grand featured ninety-seven keys and spanned eight octaves. First manufactured in 1900, for the next nine decades, it was the only concert grand piano in the world to feature ninety-seven keys. The additional keys were bass notes which accounted for the piano’s distinct sound.

The following Model 225 consisted of ninety-two keys and spanned seven and a half octaves. The expanded keyboard was produced following a suggestion by the Italian composer Ferruccio Busoni, who wished for a piano that could accommodate his transcription of Johan Sebastian Bach’s “Partita in D minor for solo violin”.

Following numerous take-over bids throughout the twentieth century, all stocks of the company were sold to Yamaha in December 2007.
