Vienna concert grand and Imperial 97-key specialist · Bösendorfer tuning, regulation, voicing · Islandwide Singapore
Bösendorfer of Vienna has been crafting pianos since 1828 — among the most tonally distinctive concert instruments in the world. The Bösendorfer Imperial, with its extended 97-key keyboard reaching below the standard bass range to a low F, is one of the most recognisable instruments in classical music. Piano Repair Singapore provides specialist service for Bösendorfer grand pianos in Singapore, including the Imperial and Vienna series.
Bösendorfer's construction philosophy differs fundamentally from American and Japanese instruments: the spruce resonance case — the entire inner rim — acts as a resonator, contributing to Bösendorfer's characteristic warm, orchestral tone. This construction makes the instrument particularly responsive to humidity changes. In Singapore's climate, regular maintenance and a managed environment are especially important for these instruments.

Yes. The Bösendorfer Imperial has 97 keys — the nine extra bass keys are typically covered by a lid panel in performance to prevent accidental striking. We tune all 97 strings correctly, applying appropriate temperament to the standard 88-key range and tuning the sub-bass strings (BB♭ to F♯) to their correct pitches at precise octave intervals from the standard bass register.
Bösendorfer piano tuning costs S$180–S$250 in Singapore depending on model and condition. Imperial 97-key models are at the higher end of this range due to the additional tuning work required for the extended bass section.
We recommend Bösendorfer pianos be tuned every 3–4 months in Singapore's climate. Bösendorfer's spruce resonance case construction is particularly sensitive to humidity variation — the entire inner case participates in tone production and is more affected by Singapore's humidity swings than instruments built with standard hardwood rims. More frequent tuning maintains pitch stability and helps monitor the instrument's condition.
