The Clavinova CLP-645 delivers the authentic feel and response of a real acoustic piano. Yamaha calls it Real Grand Expression — and they should know. They've been perfecting their piano-making craft for over a century, and their grand pianos are standard equipment in top studios and on premier concert stages worldwide. Packed with unique, expertly integrated Yamaha technologies, the Clavinova CLP-645 delivers renowned expressive capability as it precisely executes your nuanced musical intent through the responsive touch of its keys and the feel of its pedals. As you play, you'll revel in the experience of playing an acoustic grand piano.
The material used for Natural Wood X (NWX) keyboards is cut from wood that has been carefully dried specifically for use in making musical instruments. Yamaha's NWX key action gives you incredibly realistic grand piano touch and response. Fitted with the same hammer system and springless mechanism as a grand piano, NWX keyboard action gives all keys an authentic resistance that increases from the top register to the lower — just as on an actual acoustic piano. This means that you can pound out thunderous low notes with your left hand on the Clavinova CLP-645 and let the fingers on your right dance on the high notes. It also features Yamaha's 3-sensor technology, which accurately senses and interprets the behavior of the keyboard for superbly realistic feel and response. The NWX keyboard features an escapement mechanism that gives you the feel of an acoustic piano as it goes through the let-off of the jack and the fall of the hammer when a key is played very softly. Add to that the superb feel of Yamaha's synthetic ivory and ebony keytops, which mimic the tactile surface of the keyboards once used in the finest pianos. Yamaha uses a highly absorbent material that gives you the ideal texture and feel while preventing your fingers from slipping even after hours of performing. Take it from Music Experience, the Clavinova CLP-645 is a keyboard that begs to be played.
The Clavinova CLP-645 grand piano voices are sourced from premium, hand-selected Yamaha CFX and Bösendorfer Imperial concert grand pianos tuned to perfection by top professional piano tuners. Only then were the sounds meticulously sampled in varying velocities, for a stunningly realistic grand piano sound with smooth tonal transformations perfectly matched to key pressure. From staccato to legato, you get superbly expressive sound that responds beautifully to your touch. Featuring Yamaha Smooth Release technology, CLP-645 gives you realistic crisp staccatos and luxurious legatos, for nuanced response just like a real grand piano.
In a process analogous to that of an acoustic piano, the Clavinova's body materials and speaker positioning are meticulously calibrated to ensure that the instrument resonates optimally. To achieve a sonic image uncannily close to a grand piano's, the CLP-645 employs tone escape ports in multiple locations throughout the cabinet; this allows the sound from the speakers to be projected naturally to the listener's ears without getting trapped inside the instrument. The body of the CLP-645 has Acoustic Optimizers that control tone and regulate the flow of sound, for natural, smooth sonic richness across the entire keyboard range.
The Yamaha CLP-645 has a 16-track, 250-song recorder to capture your creativity. When it's time to share your music, simply record your performances to a USB flash memory device as a WAV audio file. With 16 tracks and the CLP-645's 34 high-quality instrument Voices, you can build up complex arrangements for compelling demos or flesh out your song ideas.
You can't always rock out at home without disturbing your family or roommates. Of course, the Yamaha CLP-645 sports dual headphone outputs, but for those occasions when you prefer not to use 'phones, the CLP-645 lets you adjust your speaker volume while compensating for the loss of bass and treble you get at lower levels. Yamaha calls it Intelligent Acoustic Control (IAC); we call it brilliant. IAC acts like the "Loudness" contour on vintage hi-fi receivers, boosting highs and lows at lower volumes so you enjoy balanced sound at any setting.
The CLP-645 is the mid-range Clavinova CLP, offering powerful sound and a superb Natural Wood (NWX) keyboard action. It features the sounds of the flagship Yamaha CFX concert grand and the Bösendorfer Imperial that sound pristine through its bi-amplified internal sound system. And the Clavinova Virtual Resonance Modeling emulates the more complex elements of playing these acoustic instruments. Bluetooth audio lets you stream music from your portable smart devices, wirelessly! Record your own performances and compositions using the built-in USB audio recorder to archive your musical achievements or share them with friends and family. Traditional on the outside but modern inside, this instrument is a great piano for musicians of all skill levels.
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.
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.
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.
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.
Natural Wood X (NWX) keyboards are created using unrivaled expertise that Yamaha has acquired through more than a century of crafting fine pianos. Just as with grand pianos, the material used for Natural Wood X keyboards is cut from wood that has been carefully dried specifically for use in making musical instruments. Only the best wood from the finest part of each tree is selected, resulting in a keyboard that is more resistant to buckling and warping than common laminated wood keyboards. The Yamaha Natural Wood X keyboard features the same action and three-sensor configuration as Graded Hammer 3X keyboards, which accurately senses and interprets the behavior of the keyboard for a response that feels very similar to that of a grand piano. This allows you to vividly perform smooth, flowing passages or light trills, techniques used in many pieces such as Für Elise.
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 NWX 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 Yamaha has fitted Keyboard Stabilizers 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 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.
Yamaha’s 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.
You can play music through the audio system on the Clavinova by using a Bluetooth-enabled smart device. You can stream audio data such as mp3 files. You can enjoy playing along with any songs on your smart device, and you can even share your Clavinova performances.
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 16 tracks for simultaneous playback, so different hands can be recorded separately or overdub parts with different Voices.
Record performances to USB flash memory and create audio files* you can save and play back on a computer, share with friends or create a CD. Connect the Clavinova to a computer or a USB memory device to manage your library.
