Experience the sound of two legendary concert grand pianos with the Yamaha CFX & Bösendorfer Imperial at a combined value of over £300k. Both models have their own iconic tone opening up new sonic possibities and sparking inspiration.
Virtual Resonance Modeling (VRM) is an advanced algorithm that models the resonating parts of the piano (such as the soundboard, frame, strings etc.) and allows the player to have the ultimate control over the individual parts to design their perfect sound.
A Yamaha CFX concert grand sampled using a 'binaural' stereo microphone (shaped like a human head) and positioned in the seated position of a grand piano, this puts you in the exact spatial position to experience the full stereo sound of Yamaha's flagship piano.
Uses the same hammer system and spring-less mechanics as a grand piano resulting in a natural feeling keyboard action, complete with escapement which (in a grand piano) moves the hammers away from the strings quickly after they strike them.
What Yamaha say...
Distilling the very essence of a grand piano into
the feel, tone and touch to resonate with
the aspiring pianist in you
The new CLP-600 Series captures the soul of a remarkable concert
instrument in a digital piano to deliver a grand piano performance in
a more personal environment. Play with the voice of the CFX, the finest
Yamaha concert grand piano. The Clavinova CLP Series also offers the unique
sound of a Bösendorfer Imperial.
Introducing GrandTouch and ebony keytops
The newly developed GrandTouch keys offer more responsive touch and a
greater dynamic range than ever before. The pianist can experience a natural,
balanced response from the tip to the very back of each key. The black keys
on all keyboards of the new CLP-600 series are finished in ebony. Synthetic
ivory key tops reproduce the tactile surface of the real ivory keyboards that
were once used in older acoustic pianos. It features highly absorbent material
that prevents fingers from slipping even after hours of practice, while retaining
the ideal texture and feel.
Real grand piano tone
Two world-renowned concert grand pianos in one. The powerful tone of the
flagship Yamaha concert grand, the CFX, and the unmistakable sound of a
Bösendorfer Imperial are available at the touch of a button. In the CLP-685 you

from the CLP-635 upwards include an Upright Piano voice.
Physical modeling techniques provide authentic reproductions of internal grand
piano reverberations and offer rich, endlessly varying expressive capabilities.
VRM reproduces the resonance characteristics of the strings for every note on
the grand piano keyboard in nuanced detail.
Enhanced Virtual Resonance Modeling (VRM)
for rich and bright sound
In a grand piano, sound resonates throughout the body of the instrument,
producing a rich reverberation that envelops the listener in sound. These
phenomena are reproduced perfectly in the Clavinova through Yamaha Virtual
Resonance Modeling (VRM) technology. The piano body resonates just like an
acoustic piano. The acoustic system of the Clavinova reproduces the sensation
of the entire piano vibrating, just like the feeling of playing an acoustic piano.
Even headphones produce a larger than life experience
Thanks to advanced binaural sampling technology, you can enjoy the highly
realistic sensation of playing a concert grand piano even when you are using
headphones. For the first time Yamaha's advanced binaural sampling technology
is now available on the Clavinova. The technology uses samples from the CFX
recorded with specialized microphones that capture locational information and
other nuances discerned by the human ear. The resulting sound is so natural,
so enveloping, that you'll soon forget you're even wearing headphones at all.
Built-in Bluetooth audio
You can play along with music from your favorite music apps via the Clavinova's
built-in Bluetooth interface.
The sound of some of the finest concert grand pianos in the world
With two world-renowned concert grand pianos available at the touch of a button, the CLP Series lets you choose the perfect piano tone for the music you want to play. Offering far more than just sampled sounds, the CLP-600 Series reproduces the Yamaha CFX concert grand and the legendary B?sendorfer Imperial in meticulous detail.
The powerful tone of the acclaimed Yamaha CFX
Yamaha’s flagship 9’ concert grand piano, the CFX, offers sparkling highs and a powerful resonant bass with a sound that projects to the furthest reaches of any concert hall. The CFX was played by the winner of the prestigious International Chopin Competition in 2010, and has since gained recognition as one of the greatest concert grands of modern times.
The legendary sound of a Bösendorfer Imperial
Originally founded in 1828, Bösendorfer holds a unique position amongst piano makers as the only manufacturer in the world still utilizing the Viennese tradition of hand-crafted design that produces the uniquely warm bass, singing treble and rich tonal colors known as the “Viennese Sound”. The development of Bösendorfer pianos has been influenced by such famed composers as Brahms and Johann Strauss, resulting in an instrument lauded as the only piano capable of withstanding the frenetic playing of Franz Liszt.
Remaining true to this legacy of meticulous design and implementation, each Bösendorfer instrument is painstakingly crafted over many hours at the hands of highly-experienced craftsmen. In 2008, Bösendorfer became part of the Yamaha Group and in 2014, the revered tone of the Bösendorfer Imperial was featured in the Clavinova CLP Series.
Built on a Legacy of Concert Grand Piano Craftsmanship
Grand Piano keyboards are characterized by a light feel when played gently, and a heavier feel when played with more strength. Conversely, a non-grand piano keyboard has a uniform resistance regardless of whether the player uses a gentle or heavy touch. This has traditionally been one of the most significant differences between the touch of a grand piano and that of a digital piano. However, when developing GrandTouch keyboard action, Yamaha sought to reproduce the true key resistance that is unique to the grand piano, with greater fidelity. The result is an instrument with a more responsive touch, offering a greater dynamic range than ever before. Now you can experience a much more controlled, nuanced sound when playing softly, or powerful, brighter tones when playing with a stronger touch — just like that of a grand piano.
Achieve True Balance
Pianists prefer grand pianos not only because of the way they sound, but also because of the way the keys respond to their touch. When grand piano keys are struck, there is a certain weight or resistance to the touch. Similarly, when keys are released, they return to a resting position based on the balance between the key and the internal mechanics of the keyboard. It is difficult to reproduce the natural return of the keys of a grand piano in a digital piano, due to differences in the mechanics. Yamaha carefully studied these characteristics when developing the GrandTouch keyboard, and has now reproduced this fine balance in the Clavinova digital piano. The result is GrandTouch - detailed grand piano feel that allows for uniform tone control, precise rhythm and smooth melodic expression - fundamental to an exceptional musical performance.
Leverage Your Artistic Expression
When playing a digital piano, the back area of the keys may prove to be a challenge to full musical expression. This is because the back of the key is closest to the fulcrum of the action. The closer to this pivot point that you strike the key, the less leverage you have and the more strength you need to apply. The greater length of GrandTouch keys give the player MORE leverage, allowing for better expressive control, even at the backs of the keys. This is the same support length found on the Yamaha S3X premium grand piano (as of April 2017), and is the longest support length used on any digital piano.
We Didn’t Let Any Detail Slide
Our fingers are more sensitive than we think, and for pianists, the texture of the piano keys is extremely important. The GrandTouch keyboard features white keys made from the highest quality synthetic ivory, developed independently by Yamaha. The black keys are finished in synthetic ebony. Synthetic ivory keytops reproduce the tactile surface of the real ivory keyboards once used in older acoustic pianos. It features highly absorbent material that prevents fingers from slipping even after hours of practice, while retaining the ideal texture and feel. Resulting from well over a century of experience in making acoustic pianos, this exclusive Yamaha technology achieves a finish that feels natural and comfortable. In addition to the feel, the appearance and fine texture of these keys is unmatched by any other digital piano, and is sure to inspire pianists from the moment they experience it.
Our Design Philosophy for the GrandTouch Keyboard
The GrandTouch keyboard was developed with a clear awareness of the need to recreate the responsive feel of a grand piano. For instance, one of the major characteristics of a grand piano is the wide change in key touch, from playing soft to striking the keys hard. Grand pianos respond to different ways of playing with different key touches—the keys move lightly when played softly, and the keys respond firmly when played strongly.
With the GrandTouch keyboard, Yamaha has considered the key mechanism and weight, as well as the key shape and friction that occurs during key travel. In doing so, we have widened the range of differences in key touch between lighter and harder playing. This lets you naturally sense the difference between louder and quieter sounds while playing. Further, we have designed the GrandTouch keyboard to allow you to play with an expressiveness that rivals that of a grand piano, as the GrandTouch keyboard gives you tactile feedback from the time you touch the keys until they reach the keybed.
What’s more, we have included a mechanism that simulates the lifting of hammers on a grand piano, recreating the feeling of escapement at the end of the key stroke. With this, the GrandTouch emulates both the release feeling that is unique to an actual escapement mechanism, and the feeling of stopping that comes afterwards. We definitely encourage you to experience the GrandTouch’s highly realistic feeling of a responsive grand piano mechanism that keeps moving from the outset until escapement and then stops... and with this, the sense of control brought to your performance throughout the entire keystroke range.
Outstanding Piano Sound
Innovation for effortless performance - Clavinova is an innovative lineup of digital pianos that have continued to evolve while seeking to provide the touch and tone of a concert grand piano—the ultimate symbol of piano excellence. This authentic grand piano experience is the product of the knowledge and expertise that Yamaha has accumulated over more than 125 years of crafting acoustic pianos. Utilizing state-of-the-art technology to achieve grand piano quality, Clavinova digital pianos offer an inviting playing experience that is perfect for players of all levels. They emulate the touch and tone of a grand piano to make the transition from digital to acoustic piano a seamless and enjoyable one.
VRM physical modeling—the distinctive reverberation generated by the entire body of a concert grand piano - In a grand piano, sound resonates throughout the body of the instrument, producing a rich reverberation that envelops the listener in sound. This phenomena is reproduced perfectly in the Clavinova through enhanced Virtual Resonance Modeling (VRM). The original VRM calculates the various states of the strings for each of the 88 notes on the keyboard, from one instant to the next, and timing and depth of damper pedals pressed. The enhanced VRM now also calculates aliquot resonance in the upper octaves, and the full resonance of the soundboard, rim, and frame. This technology allows for vivid, bright, richly-varied expression that reflects the limitless number of factors inherent in piano performance.
From staccato to legato—superbly expressive sound that responds to the player’s touch - Featuring Yamaha Smooth Release technology, Clavinova offers the crisp tone heard when playing staccato as well as the lingering sound produced by releasing the keys more. This provides finely-nuanced response to the pianist’s playing.
Smooth tonal transformations perfectly matched to key pressure - Sound in an acoustic piano attenuates over a long time. Pianists can change the volume of the sound—as well as its dynamics—to achieve both mellow and bright tones by simply changing the pressure they apply to the keys. The Clavinova features long, carefully-sampled recordings of notes on a piano, reproduces them in rich detail and utilizes unique Yamaha technologies to achieve smooth tonal transitions in response to the touch of the player. Additionally, the Clavinova has been repeatedly tested and adjusted by numerous pianists in order to attain a performance feel similar to that of a grand piano.
Key-Off samples - The moment a pianist’s fingers are lifted from the keys of a grand piano, subtle changes occur in the instrument’s tone as the damper is lowered onto the strings to mute its sound. Key-Off samples features actual recordings of these changes, offering a faithful reproduction of the most subtle changes in the piano’s sound, allowing for a more realistic performance.
Superb Playability and Feel
The Graded Hammer 3X Keyboard (GH3X) - The touch of the Clavinova keyboard has been praised by pianists for a performance feel that makes you forget you’re playing a digital piano, offering authentic response to the force of your touch and a natural key return. Utilizing the same hammering system and spring-less mechanism as a grand piano, GH3X actions accurately reproduce the touch of an acoustic piano from the heavy feel in the lower register to the lighter touch in the upper octaves.
Escapement mechanism of Clavinova Keyboards - The escapement mechanism in a grand piano moves the hammers away from the strings quickly after they strike them, in order to prevent any interference with string vibration. This mechanism produces a slight clicking sensation when the keys are pressed gently. Since Real Grand Expression offers players superb sound, touch and pedaling, we decided to create an escapement that delivers outstanding playability, repetition, and response without impeding performance. The Clavinova keyboards feature an escapement mechanism that reproduces this sensation near the bottom of the key dip. They have been designed in such a way that the click is discernible only on the lightest keystrokes, similar to the keyboard of a grand piano. These keyboards have been adjusted to provide additional friction that balances key repetition and response without impeding performance.
Synthetic ivory and ebony keytops—a pleasure to play even after hours of performance - Our fingers are more sensitive than we think, and for pianists, the texture of the piano keys is extremely important. The GH3X keyboard features white keys made from the highest quality synthetic ivory, developed independently by Yamaha. The black keys are finished in synthetic ebony. Synthetic ivory keytops reproduce the tactile surface of the real ivory keyboards once used in older acoustic pianos. It features highly absorbent material that prevents fingers from slipping even after hours of practice, while retaining the ideal texture and feel. Resulting from well over a century of experience in making acoustic pianos, this exclusive Yamaha technology achieves a finish that feels natural and comfortable. In addition to the feel, the appearance and fine texture of these keys is unmatched by any other digital piano, and is sure to inspire pianists from the moment they experience it.
Keyboard Stabilizers—unique Yamaha mechanisms for improved keyboard stability and durability - Keyboards fulfill the vital role of transforming emotion from your fingertips into sound and therefore, must be smooth to play in order to maintain superb touch for prolonged performances. That is why Yamaha has fitted Keyboard Stabilizers to all 88 keys, offering players a natural touch and improving the stability and durability of the keyboard.
The mechanics of superior sound
Full-body resonance, just like an acoustic piano - Similar to an acoustic piano, the Clavinova is calibrated carefully, with speaker positioning and body materials checked to ensure that the entire instrument resonates optimally. For a sound image that is very close to the grand piano, these instruments feature Tone Escapement in several locations throughout the body that allow the sound from the speakers to be projected to the listener’s ears without being trapped inside the instrument. The higher-end models in the CLP-600 Series feature dedicated DSPs, amplifiers and speakers. This vastly improves sound production, ensuring that the volume and quality of sound heard by the performer is flawless, with the output from each speaker arriving at the performer’s ears in perfect synchrony.
Acoustic Optimizer - The speakers attached to the body exhibit a phenomenon in which, if nothing is done, the volume of the sound will increase due to the resonant frequency of the body. Conversely, installing pipes with the same resonant frequency within the body suppresses this resonance. Acoustic optimizers utilize this phenomenon. This improvement of the sound is something that has only been possible thanks to Yamaha‘s thorough knowledge of the internal acoustic characteristics of musical instruments.
