Imperial Bösendorfer

Extra keys

Bösendorfer built the first Imperial in 1909, following a suggestion by composer Ferruccio Busoni to build a model with an extended range. For instance, the final page of Busoni's transcription of Bach's "St. Anne" fugue, BWV 552, contains the notes A0 and G0.

The Bösendorfer Imperial features 97 keys: a full eight octaves. This is in contrast to their other extended model, the Bösendorfer 225, which has 92 keys (down to F0). The extra keys, which are all at the bass end of the keyboard (that is, to the left), are colored black so that the pianist can tell them apart from the normal keys of an 88-key piano. They were originally covered with a removable panel to prevent a pianist from accidentally playing the extra notes. While the keys are seldom used, the extra bass strings create additional harmonic resonance that contributes to an overall richer sound. Compositions have been written specifically to use the extra keys. Pianist and University of Washington School of Music director Robin McCabe explains the challenge of adjusting to the extra keys: "One's 'southern sight-lines,' so to speak, can be seriously skewed because of the extra footage in the bass. Ending a piece such as Debussy's L'isle joyeuse, for example, with its nose-dive final gesture to the low A of the piano, becomes a bit more problematic when that A is not the lowest note on the piano!" Reportedly, "[the] 290 has proved a bit of a temperamental star, sounding harsh and jarring in the hands of pianists who do not understand how to play it and marvellously refined in the hands of those who do".

Pricing and availability

Bösendorfer Imperial Concert Grand pianos, handcrafted in Austria, retail for between US$256,000 and $560,000 in the U.S., depending on finish, design and whether the Disklavier Enspire computer reproducing system is installed. (Bösendorfer's CEUS reproducing system, "Create Emotions with Unique Sound", developed in-house, is more expensive still.) In 1977, the price was reported to be $35,000, $ in adjusted for inflation.

While the concert piano market is dominated by Steinway & Sons, which signs prominent artists to a performance agreement and urges them to refrain from playing any other piano brand, performers preferring the Bösendorfer Imperial will often have that piano shipped with them while on tour.
