Crafted with uncommon care and integrity
Yamaha grand pianos have earned a global reputation as instruments of outstanding quality and value. Renowned for their eloquent expressive range, and for their reliable performance over time, they play an important role in the performing arts and music education. They are consistently among the pianos most highly recommended by piano tuner/technicians and a leading choice of pianists at all levels, all over the world.
The Yamaha reputation rests on a century-long tradition of uncompromising care and craftsmanship, supported by an unmatched range of integrated expertise, top-of-the-line production facilities, and an exceptionally skilled, knowledgeable and dedicated workforce. Our strength in the full range of relevant technologies allows us to produce virtually every part of every piano ourselves – an approach that has helped us initiate significant advances and set what has long been recognized as the industry standard in quality control.
An open dialog with professional musicians generates invaluable input that, in conjunction with sophisticated research facilities, has led to continual advances in each new generation of Yamaha pianos. Our global network offers Yamaha customers additional advantages, from cost-efficient regional manufacturing to the ready availability of sales and support throughout most of the world.
Balancing cutting-edge technology and innovation with the timeless skills of expert artisans, Yamaha pianos have come to represent an unsurpassed standard of affordable excellence. It is a standard that continues to generate ever-higher acclaim and make Yamaha grand pianos the first choice of many of the world's most discriminating pianists.
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, 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 tuner, '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.
Seasoned for Destination
Yamaha specifically seasons this piano for the U.S. market. The tuning stability, finish and overall musical integrity are enhanced over the long life expected of a fine piano.
Permanent Crown Solid Soundboard
Yamaha utilizes a process that creates a permanent crown in the soundboard and at the same time minimizes soundboard cracking. Customer can feel confident that not only will the piano last for years, but the beautiful sound of a Yamaha piano will last a lifetime.
Solid Spruce Soundboard
At the Yamaha lumber mill and wood processing facility, the finest spruce is quarter sawn; and less than 10% of the total is selected and reserved for Yamaha piano soundboards. Solid spruce, rather than laminated spruce or poplar, is the choice in all fine pianos for the best amplification of sound, best tone and sustain.
Full Length Ribs
Yamaha reinforces the crown in its soundboards by using ribs that continue to the edge of the soundboard, and are glued into the notched liner (or inner rim on the grand piano). Reinforcing the crown ensures that the tone quality will remain for years and years and improves tuning stability.
Yamaha uses V-Pro (Vacuum shield Mold Process) in casting the iron frame (plate). V-Pro plates are stronger and visually more appealing. Critical dimensions are produced more accurately than before.
Extruded Aluminum Action Rails
Yamaha engineering developed a unique Extruded Aluminum Alloy Action Rail (bearing a Yamaha patent) that is one of the best innovations for improving a piano action in the last 100 years. The usual fluctuations in wood rails that effect touch, caused by periodic weather changes, are eliminated allowing stable, long-lasting action regulation.
Each key of a Yamaha piano is individually tested and measured for the corrections needed to obtain uniform "down weight" pressure. Yamaha actions play correctly and uniformly. This balancing helps ensure a lifetime of superior touch and control across the keyboard.
Uniform Key Travel
Yamaha designs all grand and vertical pianos to have the same key travel. Regardless of size, type or model of Yamaha piano, the keyboards will always feel the same.
Yamaha uses Spruce for the keys on all models of pianos. Spruce is very light and possesses a very high ratio of strength to weight. It is ideal for key construction, even though its cost is greater than either sugar pine or bass wood. Yamaha keyboards withstand heavy use over years of fortissimo passages.
