Model Comparison *Bold shows upgrades from the previous model:
Maybe for the first time, the CLP-625 is a true Clavinova. It features the sound of the CFX and Bosendorfer Concert Grands and also includes sampled resonance to accurately recreate the resonance of an acoustic piano. Binaural sampling for the CFX means CLP-625 sounds fantastic through headphones
The hugely popular GH3X keyboard action is in CLP-625, bringing not only escapement, but also synthetic ebony and ivory key tops at a new affordable price point.
CLP-625 has a unique 20w x 2 speaker system and also features music rest clips for the first time.
Step Up to CLP-635:
Nearly everything changes when you step up to a CLP-635. The design of the cabinet becomes more piano-like alongside a new interface with an easy to use screen, and piano room. CLP-635 also features a greatly enhanced piano sound, not only benefiting from an improved speaker system, but also features the new VRM technology.
CLP-635 also benefits from more colour finishes, and more features - including many more sounds, and USB memory stick connectivity - necessary for audio recording and playback.
Step Down to YDP-163:
A step down to Arius and the YDP-163 means losing allof the Clavinova benefits. The sound and feel of the YDP-163 is entirely different to the superior CLP-625. In stepping down, the CFX, Bosendorfer and resonance technology is lost, along with speaker differences.
Design wise, the YDP-163 does not have from legs, nor music rest clips.
With two world-renowned concert grand pianos available at the touch of a button, the CLP-625 lets you choose the perfect piano tone for the music you want to play. Offering far more than just sampled sounds, the CLP-625 reproduces the tones of the Yamaha CFX concert grand and the legendary B?sendorfer Imperial in meticulous detail.
Our 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.
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.
Featuring our 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.
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.
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.
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.
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.
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.
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 we fitted Keyboard Stabilisers to all 88 keys, offering players a natural touch and improving the stability and durability of the keyboard.
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.
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 utilise this phenomenon.
This improvement of the sound is something that has only been possible thanks to our thorough knowledge of the internal acoustic characteristics of musical instruments.
Our advanced binaural sampling technology is now available on the Clavinova for the first time. The technology uses samples from the CFX, Yamaha's acclaimed concert grand piano, 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.
Once you choose the Yamaha CFX Grand Voice and put headphones on, the binaural sampled sound is automatically ready and no additional settings are required. Now with or without headphones, you can fully enjoy the concert grand experience at home.
When using headphones, the Stereophonic Optimizer lets players enjoy the dispersed sound heard when sitting in front of an acoustic piano. With the Stereophonic Optimizer, Voices sampled from acoustic pianos* appear to come from the body of the instrument. This provides a comfortable, natural experience that removes the drawbacks of performing with headphones.
*The CFX Voice utilizes binaural sampling technology
The recording function featured in Clavinova digital pianos allows you to record your performances with a single touch, which is useful when you want to review your playing objectively. Additionally, you can record up to 2 tracks for simultaneous playback, so different hands can be recorded separately or overdub parts with different Voices.
