  • Hammer design with imported German felt that is formed over select hardwood cores and then fastened to the cores with t-shaped steel wires for the maximum resilience and structural integrity.
  • Improved hammer shanks adopt the grand piano concept for the ultimate balancing while each hammer requires a minimum of five inspections to earn quality control certification.

Jack - Limited Rail

  • Limited Rail device has added for rapid reset of the Jack during the playing of high-speed passages that require continuous movement of the hammers, resulting in an enriched performance. 


  • To accurately transmit the vibration of each string to the soundboard, the bridge must be extremely strong, rigid, and resonant.
  • Kayserburg pianos feature vertically Beech and Rosewood bridges, for increased rigidity, with a solid beech cap. The bridge is dowelled and screwed to the soundboard.

Asymmetric Back Post Structure

  • Kayserburg vertical pianos have an unequal distance, asymmetric back post structure to support the difference in string tension.
  • Scientifically designed to balance the bearing capacity of each sound section, the structure provides added stability and strength.
  • Kayserburg verticals have an inner rim of solid beech and solid spruce backposts for a sound that’s warm, clean, and distinct.

Tapered Soundboards


  • For greater dynamic range and improved sustain, all Kayserburg pianos have tapered soundboards crafted entirely of tight-grained, European quarter-sawn, solid spruce from remote regions as varied as Siberia to the mountains of Central Europe are the hallmark of Kayserburg pianos.
  • Each soundboard is given years of special seasoning, then handcrafted to ensure a precise crown (natural bowing).
