While not as universally popular as those produced by Steinway & Sons, Bösendorfer pianos are regarded for their unique sound, which is darker and mellower than a Steinway grand. One particular innovation of Bösendorfer pianos is the extended bass range: instead of the standard 88-keys, some models have 92 keys, and others have 97, all of them at the bass end. While piano music typically does not call for notes below the standard range, the extra strings contribute to the piano's sound through sympathetic vibration. | While not as universally popular as those produced by Steinway & Sons, Bösendorfer pianos are regarded for their unique sound, which is darker and mellower than a Steinway grand.
