Conservatory Grand: The SK-3 excels with an extraordinary blend of superb tone and touch that has been admired by professional pianists across the globe. The custom-tapered soundboard in a Shigeru piano is made exclusively from the finest spruce, aged by the traditional kigarashi process that uses only the forces of time and nature to allow the wood to attain a state of natural balance. It is this lengthy and painstaking process that gives Shigeru pianos their uniquely rich tonal quality. Stretcher Over-Lap Integrated Design (SOLID) creates an exceptionally rigid foundation to support string tension. With SOLID construction, the pinblock is hand-fitted to the plate. The pinblock and over-lapping stretcher bar are then integrated into a single structure and solidly anchored to the rim. The resulting framework possesses outstanding strength and rigidity to ensure stable tuning and powerful tone. Identical to those used on our renowned Ex Concert Grand Piano, Shigeru Kawai Concert Agraffes are individually machined from billet brass rods to assure maximum precision and strength. The result is clear, powerful and impressive tone!
