Yamaha C1 PWH
The C Series grands have long been the heart of the Yamaha grand piano line, offering superb sound, broad dynamic range and fine expressive control. Their classic styling and careful craftsmanship make them an elegant accent to any decor.
A distinguished history of crafting pianos
Unparalleled in their beauty and musical range, grand pianos are the ultimate expression of the piano maker's art. Yamaha is proud to present a comprehensive line of incomparable grands, reflecting the very latest in Yamaha acoustic and technological advances. Embodying over 100 years of accumulated expertise, these instruments epitomize the quality, performance and value of Yamaha has long been renowned, as we enter the second century of Yamaha grand pianos.
Fully redesigned at the turn of the millennium, today's C Series grands benefit from a host of recent Yamaha advances.
Tonal quality and performance
- Refinements in copper-wound string specifications deliver purer, more perfectly pitched and harmonious bass.
- Barrel-shaped treble hammer shanks, similar to those of the concert grand, improve dynamic and tonal response.
- Bridges crafted from choice, finely grained woods, selected to complement each scale design, provide superior sound transmission.
- Rim specifications attuned to the characteristics of each model optimize strength, stability and resonance.
- Model-specific production enables more-focused tuning, voicing and regulation, for optimal long-term performance.
- Precise note-by-note strike point alignment produces crisper, clearer tones.
- Heightened precision in damper installation offers superior pedaling and expressive control.
In addition to Soft-Close fallboards, lid prop safety stops prevent incorrect prop positioning, protecting against accidental injury or damage.
A triumph of timeless artistry and technical sophistication
Today's C Series grands also incorporate all of the quality construction features found in prior C Series models.
Rims are formed from layers of select woods, laminated into shape in special presses, then seasoned to allow the wood to stabilize. Sturdy back posts are joined in a radial configuration and fitted to the rim using exceptionally strong and stable dovetail joints, enhancing both the pianos durability and the integrity of the acoustic chamber.
Iron plates, the internal frame of the piano, are cast in a vacuum molding process that virtually eliminates flaws and imperfections, then attached with an adjustable mounting system that allows precise control over string downbearing – critical for the best tonal performance. A metal tone collector connects the back posts to the plate, reflecting sound energy back through the case for a fuller, more sustained resonance.
Soundboards are crafted from select clear spruce and cured in a proprietary process that ensures a durable, natural crown. This is further reinforced with full-length spruce ribs, securely mortised and glued into the inner rim. Bridges are formed from fine-grained hardwoods chosen for optimal sound transmission, and precisely notched and pinned to carry the strings.
Produced from special steel and pure copper wire, strings are installed with the aid of special equipment for consistent, even tensioning. Duplex scaling, which tunes non-'speaking' lengths of the strings, enriches primary tones with complementary harmonics.
Pinblocks, where the tuning pins are set, are made from layers of dense hardwoods, bonded in a process that seals against fluctuations in humidity. The pins themselves have lathe-cut, rather than roll-pressed, threads, to ensure the best grip in the pinblock, and are nickel plated to resist corrosion. Together with the integrity of structural components, these features help to give Yamaha pianos an exceptionally high level of tuning stability, assuring better sound between tunings and requiring minimal regular maintenance.
Built to the highest standards to assure lasting value
The legendary Yamaha action mechanism is built to ultra-precise tolerances on aluminum alloy rails – unaffected by changes in temperature or humidity – for superb response, rapid repetition and years of trouble-free playing enjoyment. Designed for each model, hammers are made from top-quality felt, glued and T-fastened to hardwood heads and shanks, and profiled to match the characteristics of each model. Matched key sets cut from solid spruce blocks are fitted with durable hardwood key buttons, faced with optimal tactile surfaces, and precisely balanced and laser-leveled for uniform travel and response.
Yamaha piano cabinetry is designed and constructed for long-lasting beauty, with a multi-layer polyester or lacquer finish that provides maximum protection against wear, sun, heat, spills and humidity. All fittings, including solid brass pedals and casters, are engineered for both beauty and functionality, with special protective features like Soft-Close fallboards and lid prop safety stops.
Finally, every Yamaha piano undergoes exceptionally thorough preparatory procedures. Skilled technicians tune, 'voice' and regulate each instrument repeatedly over the course of construction, aided by a 'mechanical pianist' that plays every key hundreds of times, enabling the strings and action components to normalize between these procedures. Each instrument is allowed to rest in a controlled environment approximating that of its destination, then sealed in an airtight envelope to ensure optimal condition on arrival.
The end results of this painstaking craftsmanship are instruments at the peak of their musical potential that will provide generations of pleasure to their new owners – pianos, in short, that live up to the superior standards that Yamaha owners expect.
